its where you fucking lay down on the side walk with your ass exposed on a really hot day and have your friends grandmother cook eggs on it and sell them at walmart, keeping them heated in an easy bake oven. It helps not to get shit on them or fart in the old women's face, because she could die from inhaling toxic gases.

Get the Underboob square lego eggs mug.
An egg that is pushed so god damn hard that it is forced into an square like shape.
You can also make a square egg by acting like its dad and beating the shit out of it.

Also another insult for calling someone gay
