Teenial

Being in denial of such epic proportions that mere denial is not descriptive enough a term to contain it.

Man, you are in such denial it's amazing--you are in teenial.

Digrass

A portmanteau of digress + grass (marijuana). Meaning to take time off to smoke marijuana, or to explain going off on a weird conversational tangent as being the effects of marijuana.

(In the midst of a conversation)

Dude, remember at Frank's last week, I was smashed man--but I digrass.
