The Pizza Pie 

An advanced technique used by the ancient italians to stimulate the anus and vagina simultaneously. The move, performed only by the bravest of the brave, involves placing the left fist into the anal canal and the right fist in the vagina. Move each fist vigorously in the up and down direction, as if running. The move has been carried down from generation to generation and has been commercialized in the pizza making industry. Almost all pizza makers have perfected this move, just ask their wives.

Hey Antonio, after the pizza pie you gave me last night, I can hardly walk!

Someone that does something stupid.
Someone who is mentally challenged.
