kentucky boiler 

noun. when sitting on a cold hard surface (e.g. metal folding chair) you fart the type of fart where a quarter could pop out of your asshole and it sounds like a little man is blowing kisses out your asshole.

That Kentucky boiler i dropped earlier made a tie-dyed ring in my boxers.
