Common street slang, specifically in the Upstate NY region for a vape or e-cigarettes. Used mostly by the youth. May be referred to as a boo thang as the full term.
“Yo bro do you got a boo?”
“Nah twin but I heard Bob got one!”
“Shit twin I gon see if I can smack his boo thang my guy”

Eugene “Boo” Corrigan is the crooked, delusional, and incompetent head chairman for the College Football Playoff Committee who made the unjust decision of snubbing Florida State of their rightful position to advance to the playoffs in 2023. Florida State holds the title of P5 champions and they are undefeated with a 13-0 streak. Boo forgot that football is a team sport. He seems to believe that Jordan Travis is his own football team and due Jordan’s injury Florida State is trash. Eugene got the name “Boo” because his work ethic and inability to make rational decisions is “booed” upon.

Something very ugly or just straight up disgusting. Like comparing something to murky poop water or diarrhea. For example. The water in porter potties. Sometimes used in reference of something that sucks
