Women who seek out jersey wearing athletes (i.e. bicyclists, basketball players, football players, etc.) for sexual encounters, essentially sports groupies. See: Bullpen Beef
The Jersey Jumpers were sitting in the bleachers trying to hit on members of the bicycling team, just like the Bullpen Beef we saw the night before hitting on the Oakland A's bullpen players.

Get the Jersey Jumpermug. a person who jumps on to the bandwagon, purely because it's popular and attempts to show another person this hype, when in fact that person is well aware of it, before the hype.
"yo, have you seen those 'yo momma' jokes? they are sick man! I know so many right now..."
"you are such a hype jumper."
