When a guy at a bar/club can't hook up with a hot skinny chick by the end of the night and they have to look for a fat and/or ugly one. They must go Piggin
A fat couple in bed decide they want sex, so the man says 'hmm honey shall we do it doggy style tonight?'. The woman replied 'oh yeah baby, do me hard!' piggin
wink
The act of going doggy style with your woman, and sliding it out of hole one and going into hole two "unexpectedly". When she screams out in pain, you shove an apple into her mouth, like cooking a whole pig.
I have to go to the store tonight to get an apple, I'm gonna try Piggin my girl tonight.
