slippery sandwich
Is when a man or a woman spreads another woman's butt cheeks and spreads mayonnaise or miracle whip in between her buns.
Ive got everything in my refrigerator to make the best slippery sandwich except that girl!
Slippery chicken sandwich
A threesome with 2 men and 1 woman with the woman being in the middle whilst lathered in Franks Red Hot Sauce.
Yea bro, that slippery chicken sandwich with Lisa made me piss spicy pee.
