Schwake

The small, dry pieces of a bag of low-quality cannabis known as schwag, that collect and reside at the bottom of your bag until you're left with nothing but these small pieces. At this point, you are left with a bag of schwake. A very unrecommended choice by which to get high.

The word is a portmanteau of schwag and shake.

"Hey, it's your hit on the bowl of schwake."
"No thanks, I would prefer to not nauseate myself by smoking that disgraceful excuse for a bowl."
