Sillycorn 

A mental condition that occurs late at night when you have been up for way too long. Everything becomes funny, even though it wouldn't be funny at all in the daytime.

Person 1: Quit touching me queer! You're really pissing me off!
Person 2: Well, you're a...vagina face!
(Everyone in the room cracks up)
Person 1: Man we are really sillycorn.
Person 2: Fuck yeah, hand me another Red Bull.

Oh, you're such a sillygoose, Rodney.
