Boo Hiss

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”.
