When a guy eats a girl's snatch like thanksgiving dinner whilst she shits on the John.
Man last night was crazy. Me and your sister got wasted and I gave her a Thunderdome while she pinched a loaf.

A sexual act synonymous with "The Devils Threesome" i.e.two guys one girl. But the difference is at some point one dude bails the scene leaving his bro to seal the deal. Hence two men enter...one man leaves. (By extension, two men enter...one man comes. Get it??)
Guy 1: "Remember that time we Thunderdomed Sarah?"

Guy 2: "Yeah, I lost interest and had to run. At least we still have the video".

A bathroom or restroom one uses, usually at work, to take the biggest dumps of the week in, causing ungodly odor and noise. Like the Thunderdome in "Mad Max Beyond Thunderdome", "Two (men) enter, one (man) leaves."
Man, I gotta go so bad. I'm gonna take my chances in Thunderdome.

This is a prison so dangerous from hand to hand combat, it is like a Mad Max movie.
If you get shipped to Trousdale, be ready for a Thunderdome prison!
