Puffcrash 

When you smoke marijuana and you must take a nap.

The girl had just finished eating a bag of doritos and then puffcrashed onto the couch for an hour.

PuffClaph 

A sneaky kind of fart that leaves your anus, sneakily creeps as a bubble along your sweaty crevice (forwards or backwards) and then finishes with a loud pop when it finally escapes.

I can't exercise after a big Tex-Mex meal; I'm sure to have a PuffClaph in Jazzercise..
