Lancebag 

A person who rides his bicycle on public excercise paths as if they are competing in a major race. They are typically subpar riders and are rude. Sometimes they wear yellow jerseys.

Mike: Did you see the cyclist in the park on Sunday wearing a yellow jersey and yelling at all the pedestrians?
Ike: Yeah. He's such a lancebag. What did he think it

was the Tour De Central Park?
