i hate people who are dumb asses. If some douchebag was waving his hand in my face i would break his wrist, just because your getting stone doesnt mean you enter temporary retardation. I swear people just dont understand.
You should've turned around and promptly punched that dumbass in the head. If he has the nerve to ask why you hit him, simply shrug and reply "It must be the reefer madness."
