Essentially a rim job with a bonus. A Slim Jim is inserted to the rectum and the partner proceeds to eat the Slim Jim until it is completely gone. Rim job follows.
Becky went to the store and got a Slim Jim to use for my RimJim tonight.
The worst show ever made. John Belushi's talentless brother plays a fat ugly ass slob inexplicably married to a slim blonde model. Literally more laughs in Schindler's List.
Mike: It's 8:00, my favorite show According to Jim is on!
Steve: wtf that show sucks!
Mike: I huff paint fumes and my parents are brother and sister.
