Ketterweed 

Marijuana that is of inferior quality, containing little, if any, THC or cannabanoids; alternatively used to describe any substance that resembles marijuana but is actually a different (non-psychoactive) herb. Use of the term appears to be restricted to central Ohio, Baltimore, MD and the Cleveland-Buffalo-Rochester corridor.

Mom, Toss me your car keys. My dealer sold me some ketterweed and I'm gonna drive over there and burn down his f-ing house.

ketterjedn 

named after the nastiest person living in the northern hemisphere, a so-called "ketterjedn" is a specific type of creature-like sub-human living in such a great amount of agony and pain, the most common words leaving its mouth are miserable sentences like "i hate my life" and "strongly considering re-opening my wow account".

"mike, stop being such a dick to your mother, you're acting like a ketterjedn"
