When you want a spicy enema (butt chugg), but you dont want to get wasted... you just want a nice tingling sensation in your innards, you grab a diet coke and a few mentos. Carefully place the mentos in your mudslide, once inserted start shaking a two liter of diet coke, open the top and sit on the bottle in one swift motion then wait for the fireworks to begin! Dont pull off too soon, because your partner can drink that up! Two girls one cup? Nah two people, one two liter... and a couple mentos. Enjoy!
Sue: Bill, grab the diet coke and mentos.
Bill: You thinking what I'm thinking?
Sue: I want you to drink my ass pop tonight.
Bill: Aye Baby! It's Muddy Sprinkler time!

When scissoring with your partner, you simply tap your bholes together. Much like an Eskimo kiss, just with your bholes.

The same concept as the "wet willy," except instead of sticking the finger in their mouth, the attacker first sticks their finger in their bum
"I was sitting in my room the other day when I thought my brother gave me a wet willy. It was only after i smelled something putrid did I realize that it was really a Muddy Matthew"

Similar to eskimo brothers, except for gay men. When two or more bros have gaped the same dudes poop chute.
John was so ecstatic to tell Bill he finally reamed out Terry after the club Saturday night and they are finally Muddy Buddies!

The act of jumping as high as you can on a bed or trampoline, defecating mid air, and landing in it.
