Olympic baton
Similar to a baton but instead of just hooking up with random guys, it's a girl who gets passed around from guy to guy within the same group of dudes.
Dude 1: I just realized that girl I went out with last night has been with 3 other dudes I'm friends with...
Dude 2: Well let's give her the gold. She's definitely an Olympic Baton.
