Froing (v.) - the act of moving or walking with a jarring or stumbling manner due to major impairment in one's motor skills / hand-eye coordination. Most often used for cannabis intoxication, but can also be transferred to alcohol intoxication due to similar clumsy movement.
Primary use:
Dude, check him out! He's so blitzed he's already froing!
Secondary use:
He got that scar by getting plastered last year on 17 bottles of beer, started froing all over the house and finally tripped and hit his face on the heating radiator.
