When your girl shaves her pussy hair into the shape of a handlebar mustache so that when you eat her out you feel like more of a man.
I was eating out Barbara the other day, and her Handlebar Muffstache was so good that it made my dick twice as hard because I felt like more of a man.

Similar to the mustache that can sometimes be found on the face of a man, a muffstache is also a patch of coarse hair, only instead of being found on the face of a man, the muffstache is located just above a woman's genitals. Also known as female pubic hair.

Frank: "It was awesome, other than the fact that she had a muffstache, and it kept tickling my nose!"
Carl: "What? Tara doesn't shave her vag? Tell her to shave! It's not 1804 anymore."
Frank: "Yeah, I definitely have to say something!"
