Get the Boomug. Used by fans at sporting events to respectfully let referees know that the pervious call was horseshit. Will not get fans kicked out of games and clearly expresses what you think of the call. Can be used with Outrage.
At a soccer game, the referee fails to call a clear foul. Fans quickly yell “ Boo Hiss” followed-up by “Outrage”.

Get the Boo Hissmug. 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”
