The term Chimney Stomp is where Santa has to take a massive shit so he takes in in someone’s chimney and proceeds to stomp it down until said shit is down the chimney.
(v) {pres. part.}: The insertion of a prolapsed uterus into a vagina or anus during sexual intercourse, usually in place of a penis.
At first the sight of the saggy uterus was sickening, but when she stated chimney sweeping the guy, I couldn't help but feel strangely aroused, if not dead inside.
This occurs when you drop ass while wearing heavy clothing or coverall type clothing. The stench dosent escape throught the fabric. It travels up and vents out around your neck like smoke out a chimney.
