lily-pad lover

A person, most oftentimes female, who keeps a lover or steady until they find a new lover or steady that they feel, in some way, shape, form, or fashion, is an improvement from the older lover or steady.

John is gonna have to wake up and get a clue. I done told him about Betsy being a lily-pad lover. Now he's done got his heart broke cause she culled him yesterday. Shit, I saw that bitch with Doug at the sock-hop last week.
