A horrendous smelling fart that often precedes a bowel movement. This fart gathers its potency by propelling air over excrement that is currently esconced in the colon and waiting to be pushed out.
"Oh! That fart smelled so bad it must be wind over poo!"
"Watch out! I got one in the chamber so these farts are gonna be straight wind over poo."
