Slang for really, really, really, SUPER potent weed. Usually shortened to boo for ambiguity. Supposedly coined by this guy named Pimp Dog who did this amazing free-style at this party i was at.
1) "You gadat boo?"
2) "Hey bro, i burned some Boo Boo Shmack yesterday, went fuckin' blind.. turns out, my eyelid muscle permanently broke. Too much THC homie, eyes cracked for life."
