When a man is having sex missionary style and the girl farts so hard that the mans balls slap his own asshole!
I should have never fed Sally that chili.. we were banging missionary and she ripped a fierce fart and gave me rowdy Mexican Mud Flap that had my balloon knot swollen for days!

Mud Flapped. The female version of getting tea bagged in a video game after you get killed. The act of squatting up and down on a players head after killing them to show your dominance.
After I was killed in my game she mud flapped me to establish her dominance and let me know I am trash.

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.

As Jose was ass fucking Laura, he thought “thank god I have my balls as mud flaps. Otherwise that shit would have been everywhere.”
