Crumb whore
A crumb whore is the girl at the end of the night that trolls the bar or party for that last minute bang. The girl who looks to clean up the scraps. Once she finds her prize she will make a nibbling noise.
"That crumb whore looks hungry, she won't be going home alone tonight"

one who fucks for mere crumbs!
Saw that crumb whore Tracy at the club last night.
