hi-def

The state of being so high, usually on marijuana, that the stoner becomes deaf. Often associated with being so absorbed watching HDTV that everything else is ignored. Inspired by a high deaf kid who gets deafer as he gets higher.

Peter was so hi-def that he couldn't even hear the police siren as they pulled up to arrest him for dealing hella-weed.

True Def

One who doesn't have a clue what the hell they are saying.

A kid that goes to Starkville and gets messed up.
Dumbs that have trucks but don't use them.
People that dip.
Anyone that thinks they are a bulldog.
Anybody that chides

Wow, that kid is being a true def!

Ultimo-Def-Rad

the Prophet of the Rad Harmony Faith; a Def-Radder that has had a Serious Injury due to a Drinking accident; a person that is Ultimately and Definitely Rad; the Raddest person that walks the planet; the Lame-Slayer of Slutty Utah;

"Boo became Ultimo-Def-Rad when he decided to Light a Shot that was in his Mouth on Fire. Causing him to Cough Fire all over him Self"

"The Slutty Martinez Brothers were considered Ultimo-Def-Rad after a Night of drinking resulted in a Broken Leg, and a Man-kini Fire Dance gone wrong."
