Mud Flapping

Mud Flapping is when a guy challenges or questions another guy’s manhood based on the former not being capable of a feat that he himself has just proved himself unable to accomplish

Example:

MudFlapper: “Hey bro, you got a knife I could borrow?”
RealMan: “Sorry bro, I don’t have it on me.”
MF: “What?! A real man always carries a knife!”
RM: “YOU don’t have a knife idiot. Stop all your mud flapping and get out off my property.

Fat Flapping

The action of getting volatile and angry over a minute and niche thing of something that's praised.

Friend 1: Hey, did you hear about that new Left 4 Dead 2 update?
Friend 2: Yea, I hear it's awesome! Though I did hear one dude complain that the update ruined his mods.
Friend 1: Don't mind him, he's probably just some fat flapping weeb who's upset that his 150 Hatsune Miku mods don't work no more. Let's go play!
Friend 2: Ight, bet!
