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!
