laying an egg

to poop your pants; to fart; a stinky bowel movement.

"Jingle bells,
Batman smells,
Robin laid an egg"

Clearly, by "laying an egg," the writers of this song meant that Batman was smelly because Robin had shit his pants in the Batmobile.

Laying an egg

The act of pulling one of your testicles up to your ass and showing it to someone while simultaneously mooning them.

I just laying an egg(laid) in front of greg over there and he’s crying now.
