An activity in which participants deficate in the same toilet bowl without flushing. After a large accumulation of feces, and the scent becomes unbearable, you have achieved a witches brew. Originated at valley stream north.
Referring to a situation when a gentleman has not ejaculated for a long period of time. His baby batter has been brewing and thus is quite pungent and foul to the taste.
Dude, I have been stewing this witches brew for almost a month in anticipation of blowing it all over that whores face.
I busted a five roper of witches brew on that bitch and she almost vomited from the necrotic odor.
