Slippery Slug Sex 

When two people of any sex completely cover themselves in olive oil and rub against each other then you put a bodily fluid of your choice in the persons mouth they wash it around they spit it in your mouth and add something else. It keeps going back and forth until one of you quits at that point the winner gets oral. Also known as S.S.S

"Man me and levi did some slippery slug sex last night he gave me a great blowjob after he puked all over my ass"

Walking the slippery slug

The act of the man having to get up and go find a cum rag when nobody thought to get one ahead of time. Named as such because there is usually a slug trail from the bed to where the guy finds the necessary absorbent item. Often a t-shirt or towel is the first thing they find.

Ginger forgot to get a cum rag, so Chad had to resort to walking the slippery slug to the hamper to grab a shirt.

Slippery slippery slugs 

When you and a friend both take a bus full of Xanax, and get drunk. Then strip butt ass naked and cover each other in Vaseline and squirm around on a smooth surface, such as a tile floor. Leaving a trail of Vaseline across the floor. This is a completely non-homosexual act.

Harrison: “Hey bro you down for a game of slippery slippery slugs at my place around 8?”
Joey: “chaaa bra I’ll get the Xanax and the booze, you get the Vaseline”

Harrison: “fuck yeah bro”
