1. A vehicle operable by an intended user on a ground surface, said vehicle comprising: a vehicle body for supporting said intended user, said vehicle body defining a body front end and a substantially opposed body rear end, said vehicle body also defining a body longitudinal axis extending between said body front and rear ends;a front wheel and a rear wheel, said front and rear wheels being rotatably mounted to said vehicle body respectively substantially adjacent said body front and rear ends so as to be rotatable respectively about a front wheel rotation axis and a rear wheel rotation axis, said front and rear wheel rotation axes being orientable substantially parallel to each other and substantially perpendicular to said body longitudinal axis; andan auxiliary wheel mounted to said vehicle body so as to be rotatable about an auxiliary wheel rotation axis, said auxiliary wheel rotation axis being angled with respect to said front and rear wheel rotation axes;said auxiliary wheel being movable between a retracted position and an extended position relative to said vehicle body, wherein, when said vehicle is operatively supported on said ground surface by said front and rear wheels, said auxiliary wheel is closer to said ground surface in said extended position than in said retracted position. 2. A vehicle as defined in claim 1, further comprising an auxiliary wheel carriage to which said auxiliary wheel is rotatably mounted, said auxiliary wheel carriage being pivotally mounted to said vehicle body so as to be pivotable about a carriage pivot axis between a carriage retracted configuration and a carriage extended configuration, said auxiliary wheel being in said retracted position when said auxiliary wheel carriage is in said carriage retracted configuration and said auxiliary wheel being in said extended position when said auxiliary wheel carriage is in said carriage extended configuration. 3. A vehicle as defined in claim 2, further comprising a biasing element biasing said auxiliary wheel carriage toward said carriage retracted configuration. 4. A vehicle as defined in claim 3, wherein said auxiliary wheel carriage defines a pedal area for allowing said intended user to press thereonto to move said auxiliary wheel carriage from said carriage retracted configuration to said carriage extended configuration. 5. A vehicle as defined in claim 2, wherein said auxiliary wheel carriage defines a carriage proximal end and a substantially opposed carriage distal end, said auxiliary wheel being rotatably mounted to said auxiliary wheel carriage substantially spaced apart from said carriage proximal end, said auxiliary wheel carriage being pivotally mounted to said vehicle body substantially adjacent said carriage proximal end. 6. A vehicle as defined in claim 5, wherein said carriage distal end is laterally further away from said body longitudinal axis than said carriage proximal end. 7. A vehicle as defined in claim 2, wherein said carriage pivot axis is substantially parallel to said auxiliary wheel rotation axis. 8. A vehicle as defined in claim 1, wherein said auxiliary wheel rotation axis intersects said body longitudinal axis at a location behind said auxiliary wheel. 9. A vehicle as defined in claim 1, further comprising another auxiliary wheel mounted to said vehicle body so as to be rotatable about another auxiliary wheel rotation axis angled with respect to said front and rear wheel rotation axes, said auxiliary wheel rotation axes being angled with respect to each other. 10. A vehicle as defined in claim 1, wherein a rear axis-to-auxiliary axis angle between said rear and auxiliary wheel rotation axes is fixed. 11. A vehicle as defined in claim 1, wherein said auxiliary wheel is mounted to said vehicle body substantially adjacent said body rear end. 12. A vehicle as defined in claim 1, wherein said vehicle body defines a platform allowing said intended user to stand thereonto when operating said vehicle. 13. A vehicle as defined in claim 1, wherein said front wheel is steerable by said intended user by selectively turning said front wheel to change an orientation of said front wheel rotation axis with respect to said body longitudinal axis. 14. A vehicle as defined in claim 13, further comprising a handlebar assembly operatively coupled to said front wheel for selectively changing said orientation of said front wheel rotation axis with respect to said body longitudinal axis. 15. A vehicle as defined in claim 13, further comprising another front wheel, said vehicle body including a skate board truck to which said front wheels are both mounted so as to be rotatable about said front wheel rotation axis. 16. A vehicle as defined in claim 13, wherein said rear wheel rotation axis is fixed with respect to said body longitudinal axis. 17. A vehicle as defined in claim 1, wherein said auxiliary wheel is laterally offset with respect to said rear wheel. 18. A method using an auxiliary wheel rotatable about an auxiliary wheel rotation axis to skid the rear end of a human powered vehicle rolling on a ground surface, said human powered vehicle having at least one front wheel and at least one substantially opposed rear wheel rotatable respectively about a front wheel rotation axis and a rear wheel rotation axis, said method being performed by an intended user having a weight and propulsing said human powered vehicle, said method comprising: propulsing said vehicle along a substantially rectilinear trajectory in which said front and rear wheels rotate about said front and rear wheel rotation axes with said front and rear wheel rotation axes substantially parallel to each other;contacting on said ground surface said auxiliary wheel with said auxiliary wheel rotation axis angled with respect to said front and rear wheel rotation axes, said auxiliary wheel being contacted on said ground surface substantially adjacent said rear end of said human powered vehicle; andtransferring at least partially said weight of said intended user on said auxiliary wheel;whereby, by transferring at least partially said weight on said auxiliary wheel, said intended user causes forces to be exerted on said human powered vehicle that skid said rear end in a direction angled with respect to said rectilinear trajectory. 19. A method as defined in claim 18, further comprising turning said front wheel with respect to said rear wheel substantially simultaneously to transferring at least partially said weight of said intended user on said auxiliary wheel. 20. A method as defined in claim 19, wherein said front wheel is turned toward said auxiliary wheel. 21. A method as defined in claim 18, further comprising lifting said at least one rear wheel from said ground surface.
