Muddy Butterfly 

While pounding some brown eye, you pull out your cock and smear it all over her butterfly tramp stamp.

"I was pounding Jill's ass hard last night. Then I whipped out my cock and gave that trick a Muddy Butterfly."

Muddy Butterfly 

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

"Hey baby, instead of going ATM, let's just muddy butterfly."
