trouble brew 

Used when something very, very bad, (or even somewhat bad.) could come of a situation; A much quoted line from an NKECer Global History film.

"I think I'm going to steal the Horton Mascot."
"Oh! Trouble Brew."

A highly skilled drama king or queen. An individual who can cause hate and discontent in their sleep. A professional troublemaker who says just the right things to cause a conflict. Someone who can relentlessly go from one situation to another and stir the pot. Veteran instigator.

He's the only guy I know who can make everyone at work hate one another after only an hour, he's one trouble brewing machine!
