analogous to "eavesdrop" I propose a coinage "ellpeep"

Analogous to the shift from drip to drop in eavesdrop will there be a shift from something (what we must guess) to peep?

I would, by way of getting started, guess that the ell is an extension to a house meaning that you were around an interior corner when you were ellpeeping.

Aha! The original is ellpoop. You were sitting on the throne in a newly built extension of a house (possibly an upgrade from the former outhouse) when you discovered you could overhear the conversation going on in the plumbibly adjacent kitchen.

Huh? Huh? Am I right?
