When you are you are giving a chick anal and putting your penis head in the anus and quickly pulling it out making a popping noise known as a mud pop.
I heard Jim gave Sharlene anal i think he gave her a mud pop.
When you take curdled milk and pour it on a woman's tits and you eat it off and then when you throw up she drinks it.
Steven: Dude I gave Jane a huge curdled cow. Now the bed smells like shit
Tim: Dude, that's sweet!
