Biker Bitch
A tatted-out, used-up lookin broad (sometimes a hottie) who rides on the back of a bike, smokes cigarettes, drinks wine coolers, tries to act tough, and has more balls than the insecure guy riding the bike. If she's a hottie, you wonder if she does trampish things. If she is not a hottie, you put that awful thought out of your mind.
"Hey Sam, you see that hot chick on the back of Snake's bike? No John, I don't, I see one big biker bitch ridin a sweet chrome horse, but wish she was ridin me.
Biker bitch
A really tatted up dramatic female who smokes cigarettes like a chimney and has a harsh ass voice usually from it. Usually takes charge of the situation if it involves her man because he doesn’t have balls like she does. And most likely she wears the pants in the family.
Man that Karen is one rough ass biker bitch I’m not fucking with her.
