When two or more people attempt to stall stall while in a public bathroom, resulting in many minutes of silence while all parties involved just sit quietly in their stalls.
After several minutes of complete silence I realized that I was stuck in a stallmate with the fellow next to me.

A play on the original word "stalemate", when two strangers are trying to poop in a public bathroom and cannot continue because the risk of humiliation. It starts when someone enters an empty bathroom and starts to defecate, then while in the middle of performing this action someone else walks in with the same goal in mind.
I thought i found and empty bathroom to poop in, only to be caught in a stallmate.
