This one is a snake in cheap clothing

The speaker was very angry at an adversary (another attorney) and told her husband that the attorney was smarmy. Her husband then said many of them are, and her response was, “Well, this one is a snake in cheap clothing!” This is a congruent conflation of “a snake” and “a wolf in sheep’s clothing”, both describing a treacherous or deceitful person. “Cheap” rhymes with “sheep” which may have been in the speaker’s mind. Also “all over someone like a cheap suit” (crowding someone in a flirtatious way) might be in the mix. A big thanks to Marykathryn Kopec for this one!
