very much like street BMX biking, but with a good quality, fullsize bicycle. urban mountain bikes have front-fork suspension and a hardtail, with a low-clearance top-tube and low seat. its an action sport with a small number of devoted practicioners who are recognizable by their deeply pocked, purple shins, tolerance, friendliness, maverick mentality, and sexy, athletic build.

When some little bitchboy is acting like a little tiny pee pee poo poo baby and messing up the group plans.
