a throwback term for a beat down. not to a bloody pulp, but just a quick and painful beatdown.
First main use is in the song Molly whompin' which was on the mixtape 2800 by that artist stunnaman.
Not to be confused with the term molly whomp which has a dual meaning:
1: a cock slap
2: a gang beat down that has not happened yet or is being planned.
we all just started molly whompin on this foo that raped lisa.
i molly whomped lisa last night and these guys came out of no where and started molly whompin on me
