When one has diarrhea that is so painful he screams as if possessed by demons
Guy #1: "Hey man, where is John?"

Guy #2: "Oh, he is in the bathroom. He has had the screamin' demons all night."

Get the Screamin' Demons mug.
A type of drug that is a mixture of crack,heroin,embalming fluid and LSD with sometimes traces of other drugs that is smoked.

Said to have gotten it's name because that is what it makes you see and/or act like.

Get the Screamin' demon mug.
the noise that comes from yelling into a microphone used often by metal bands
The yelling lead singer just left noise in the air. He was doing nothing but demon screamin'.
