Master of boogers

Now it may sound crazy.. but this is typically how you call friends when they act like a superior or something. You can also use it when you refer to an annoying edgy friend.

She's such a master of boogers.

Fishhead

Hmmmmmm........ you call this when you refer to someone who is short and an egghead. This dude usually wanted to be a Pisces and would want to eat some fish.

I saw a fishhead walking downstairs.
