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

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”
Joey: “chaaa bra I’ll get the Xanax and the booze, you get the Vaseline”
Harrison: “fuck yeah bro”
