Sour crack kid
When you place sour patch kids into your parters ass cheeks, (hence the “crack” portion of the name) and proceed to have them attempt to launch them into your mouth. If you wish, it can be played like a game. Whomever catches the most candies wins, with the loser having to eat the others ass.
“We were havin such a great time eating each others ass, until the sour crack kid to too competitive.”
