The Chimney Effect appears most often when you fart wearing insulated clothing like ski jackets\pants, which causes you fart to travel up you pants\jacket and then explode in your face. And in some cases it will follow you around for a while.
Guy 1 : Damn man I just had the nastiest fart.
Guy 2 : You better open your jacket or that fart is going to explode in you face.
Guy 1 : Oh shit I completely forgot about the chimney effect

Local nickname for a bloke in Beverley who used to walk around looking up at the chimneys on houses whilst laughing and getting sexual satisfaction! Also used to pace alongside trains in the station nodding at his reflection in the windows!
Darrel: "Who's the window licker with a hard on looking at my roof?"
Chris: "Chill mate, he's the Chimney Spotter"
