Bathecho 

The echo produced when someone is talking in a bathroom. Particularly amplified when on the receiving end of a cell phone call.

Dude, call me when you're done. I don't wanna hear your bathecho.

-Alternatively-

I was rockin' a deuce at the mall, and two people were talking so loudly the bathecho was almost unbearable.
