avetrol 

Very, very old way of calling someone a bastard.

Joey's mom wasn't married to his dad when he was born. I guess that makes him an avetrol.

Avatroll 

Someone who blindly believes that the Avatar movies are good, when really, they are garbage.

Only a real Avatroll would see Way of Water twice!
