I thought scumbag was any condom, used or unused.
As in:
“Heyyy mannn, len’ me a scumbag fo’ ma woman t’nite?
“Ohhh mannn, I came back to my crib an founa scumbag in my bed mannnn... an I don use no scumbags mannn”
I just took a look at Dictionary.com, and I think you’re correct! What a topic! You should start a new thread! Nah.
