lickin' the ceiling 

when you're high on cocaine or similar stuff and you go to bed and you're so excited that you can't sleep and it takes you hours awake looking up to the ceiling till you fall asleep.

-I'm gonna get cocaine from Roger for tonight, you want some?
-no way, i don't want to spend the after hours lickin' the ceiling when i get home

Licking the Ceiling 

To be REAL fuckin high...ceiling can be replaced with clouds, sky, etc.

Ron Howard: "Yo, I'm stoned as shit..."
Fonzie: "Yeah man, I'm licking the ceiling"
