turd yodeling

The deep, strangled sound one often hears when another person is working on passing a particularly, um, challenging piece of feces from their anus.

Usually quite loud and penetrating- heard through doors and over stalls. May inspire inquires of "do you need an ambulance?" "Holy shit! What did you eat??!"

Austin Powers - "WHO DOES NUMBER 2 WORK FOR??" is a great example.

In a sentence, "That dude started turd yodeling so loud in the stall I jumped and pissed on the wall!! His ass needs to eat some oatmeal!!"
