Gag name
A name that sounds real but is actually a mix of something funny, stupid, or gross, and it’s usually something you’d never want to be called.
My mom’s gag name is "Lady Waffle-Bum" because she eats waffles and smells like a trash can.
My friend’s gag name is "Sir Piddle-Pants" because he pees everywhere and looks proud.
My neighbor’s gag name is "Dude Sneeze-Snoot" because he sneezes and smells like a dead raccoon.
