crotch furnace

A heated, sticky, humid, jungle like environment which often induces swamp ass and usually conveys a smell of dirty, wet, taint juice.

This dorm bathroom is a complete crotch furnace.

That bathroom was such a crotch furnace that I had to remove my shirt while shitting.

cumberland furnace

When you have sex with your lady right before she has to drop a huge deuce, causing her lady bits to feel tighter.

I have to take a huge poo, so it might be a good time to do a Cumberland Furnace. The booty is full of logs.

German Furnace

A self inflicted Dutch Oven. Farting under your covers and pulling them over your own head to enjoy your gastro aroma!

Dude, I love smelling my own ass so much I am a frequent occupant of the German Furnace.

furnace filter

While performing sexual relations in the ever popular doggy-style position, said male retreives his dirty underwear and at the perfect interval, stuffs them unexecpectedly in her mouth as she moans. Timing is crucial in this act. A quick getaway is sometimes needed. It is required by man-law to tell all friends when this has been properly executed. Thanks JP

"Cody told me he pulled off a furnace filter last night after bar time with that milf from next door. Awesome"

Brooklyn Furnace

defecating and masturbating simultaneously

I cannot afford a conventional source of heat and therefore must resort to a Brooklyn Furnace.
