The act of vigorously introducing extremely hot slices of pizza into a woman's "taint" area. To properly perform the maneuver requires a pizza (the hotter the better), an administer, and a recipient. The recipient must disrobe below the waist and stand facing away from the administer, leaning forward slightly (bracing against a chair or countertop for impact is advisable). The administer takes a slice of pizza in hand and approaches the recipient with it as a professional bowler would approach the lane to throw, he then with all his might slaps the pizza (topping side first) into the woman's genital and buttocks area (aiming centrally for the "taint"). Bonus points may be awarded for significant distance of sauce stains traveling up the recipient's back
Person A: I feel strange asking this Bob, but why is your wife walking so strange today?

Person B: I ordered two large meat lovers last night and we played a few frames of AMF Sloptrough. She is walking like that because of the molten cheese burns I left on her business end.

A term (acronym) used in high risk adventure sports that are typically done solo or as part of small groups. When you can no longer provide assistance to your team, proper dirtbag etiquette is to let them know they're screwed and self sufficient.

"Adios My Friend You're On Your Own!" Is complicated to communicate in loud, high stress situations so the 'AMF-YOYO' term has been adopted.

It can also be communicated via hand signals if the distance between parties is too great or environmental noise prohibits effective communication. With one and form the classic middle finger, while doing a traditional bye bye wave with the other hand.
