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.
