The male scrotum (balls); What men use to keep mud (shit) off of ones penis while dropping a wicked doo-doo bomb.
Man, I had some wicked diarrhea last night; I'd have doo-doo all over dick, if it weren't for my mud flap!

When eating out your partner’s ass, s/he shits on your face. The gay men’s version of getting your Red Wings.
When all my straight buddies were sharing stories about getting their red wings, I chimed in with my story of getting my mud flaps!
Last weekend when I was going hard and heavy eating Ryan’s ass, I suddenly got my mud flaps!
