The origins of this term may come from the notion of "cherry picking" as attempting, or picking, only those things that are easily obtained, or only what suits your taste best, as a cherry might.
2) Man who seduces young virgins.
2) "You're dating another Freshman English major? You are such a cherry picker!"

"Ok, let me wheel that sucker over there. Hold on."
