A Marijuana Sauna is the act of smoking weed in any tightly sealed area where the smoke cannot escape. This causes the occupants of said area to breathe almost nothing but weed, which in turn causes them to get royally lit.

The act of running hot water in the shower while simultaneously defecating on the toilet. The purpose is to effervescently fill the bathroom with hot turd steam. May be used as a prank or to take a poo in stealth mode.
"Man, my girl Mary Beth was pissing me off so bad the other day so I gave her a duke sauna while she was in the shower."

When you or someone you know, likely a roommate turns on the shower to the hottest setting, takes a big stinky dump, then proceeds to shower. When you or said roommate leaves the bathroom, for the next 1-2 hours it will be a "dump sauna." A hot, steamy, sweaty room filled with fecal particles floating in the air.
This act may be done to disguise the act of pooping itself.
Note: The smell may be supplemented with air freshener and/or potpourri.

I was waiting to use the bathroom for 10 hours this morning, when my roommate finally left I went in and sure enough, a perfect dump sauna was waiting for me. Thanks roomie!

The act of taking a crap moments before some must take a shower in the same bathroom. Typically a tatic/ revenge against a roommate.
I knew my roommate had an 8 o'clock job interview so i woke up early, blitzed the bathroom, and gave him the belgian sauna.

When you have a bowel movement followed by a shower, the smell combines with the steam creating a poo sauna.
