Someone whose brain is severely underdeveloped — extremely slow, naive, and lacking basic common sense or awareness for their age. They come across as if they never fully matured mentally and are still operating at an early, childlike level of thinking.

Guy 1: Dude, my girlfriend admitted she’s been talking to her ex and hiding messages for weeks. I’m fucking pissed.
Guy 2: Just trust her more, bro. She’s probably just being friendly.
Guy 1: What the fuck? You're such an egg.

Egg

A New Zealand slang word for a complete fuckwit and/or retard. It can be used as a light-hearted piece of banter or a genuine anger towards someone who you really don't like.

Lighthearted context: *friend 1 does something a little stupid or dimwitted* friend 2: "aye mate, you're being a bit of an egg."

Angry context: *person 1 is being insensitive to the situation* person 2: "oi, you're being a complete fucking egg!"

EGG?!

“EGG?!” or “EGG” is used to express being shocked to see an egg on the floor as the individual’s jaw drops.

This emphasis was first used in the late 1990s by a cartoon god named Baboon who was acting in a cheap gag.
