The combination of the popular derogatory terms "wench" and "hobag." This is used to describe a girl who is sluttier than your average wench or hobag, so her sluttiness is something to be awed by.
Mallory is such a wenchbag, look at how she's unashamedly trying to get Amy's boyfriend to sleep with her.
