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!
