gay stall
When selecting a toilet to use, it is man rule not to use the middle stall and respect your fellow shitter's space. Violation of this rule, especially when other stalls are available, means you love the cock.
Guy #1: Dude, that chinese buffet went right through me. I gotta drop off the kids.
Guy #2: Looks like you're gonna have to wait. The end toilets are taken and all that's left is the gay stall.
Guy #1: FUCK THAT! I'll sneak into the ladies' room.

"i'm not gay" stall
The stall that is left open between two guys who are pissing in a bathroom. A violation of this rule, when there are ample stalls makes you gay.
I guess that dude isn't gay, he left the "i'm not gay" stall open.
