A dweebus is the combination of the words "dweeb" and "dingus." It's meant to be used to tease your dweebus friends.

This is meant to be used for someone you really love and don't mind making fun of. Spread the dweebus all around, y'all.
Person 1: "Omg you're such a dweebus."
Person 2: "What does that mean?"
Person 1: "You're just like a class A dweebus. A dingus and a dweeb all in one."

That one person who thinks they’re your ‘friend’ but no one actually likes them. Is part of the Rick and Morty fandom and usually has a crush on another of your friends.
Friend 1: ‘Wait, is THAT ‘name’?
Friend 2: Well, they’re more a Dweebus than anything else.
