look up any word, like wyd:
n. a girl who dates multiple boys in the same group at different times. She usually is never single for more than a week because once one relationship ends, she just goes out with whoever is next in line.
Dude, did you hear that Kristina went out with Sam two days after breaking up with Moe? And before that, she dated Drew, Harry, and Jack! Man... she's such a boy hopper!

A girl that goes through boyfriends gratuitously.
"Does Rachel have a new boyfriend already?"
"Yeah, she's such a boyhopper."
