Fuck someone (male or female) up the ass. Dribble the mixture out of the anus on to the delivery guy. Tame on the back , casual on the chest , edgy on the face. Could be on another player.

The unfortunate result during anal sex if the person doing the receiving does not properly prepare for the event, ie douching with a colonic or an enema, something, ANYTHING, for God's sake.
His date knew that anal sex was going to happen, but failed to prepare, and after a few minutes a Malibu Mudslide cut their evening short.

This my friend, is a new definition to happy hour at a bar. So it's basically an unruly shot method where you order a margarita slushie pitcher and then offer your lady friend to bend over and with a funnel attempt a makeshift ice luge while really tempting Montezuma's revenge on the way down.
1. My lady friend promised she had impeccable sphincter control before we attempted the Margarita Mudslide at the local bar. Boy was I in for a surprise when I tasted a little bit of funk.
2. I tried the Margarita Mudslide on the Cinco de Mayo and dubbed it, for one night only, the Sphincter de Mayo with a Latin twist.

A frugal approach to anal sex with another man. The partakers use their watery shits in place of lube, cutting costs and resulting in a shit-filled fuck fest.
Christian: "Hey, Ryan, wanna fuck my ass?"
Ryan: "Of course, Christian, I always want to fuck your ass, but I'm out of lube"
Christian: " That's okay, I have a bad case of diarrhea, let's just go the Leamington Mudslide route."
Ryan: "I like the way you think"
