A derogatory reference to a slickered up male scrotum used to a impugn that someone is a complete asshole and/or douche bag.

May also be exactly that, a lathered and slickered up male scrotum.
Dude stop hitting on my girl. You are such a lathered sack sometimes.

She couldn’t keep her cat like tongue off my lathered sack.
