KMC
Literally means/stands for Kiss Muff Cuddle. The go to move for someone who runs and locks themselves in their room once they get a girl.

Usually associated with the following two scenarios:

1) The girl they run away with is an ex girl who cheated on them and/or just fucked someone else that the guy is aware of
2) Their boys sit outside the locked door and laugh at them inside as they exchange "estrogen shots" (Note: Estrogen shots are the opposite of cum shots. Total opposite of Testosterone or any other display of sheer manhood)

The theme music to KMCing is "Butterfly Kisses" and "The Man You've Become"
Q: Yo, is he comin out with us tonight?

A: No, He's KMCing and administering estrogen shots. I think he actually might be going to Home Depot to try and buy a drain for his room cuz all the pussy juice in here is gettin a lil out of control..

WTF is that gay ass music? Oh, that's just KMC in his room

Girl: Baby, since it's your birthday I decided Im going to give you a blow job tonight
KMC: Nooooooo, I just wanna muff you all night - I would never want you to do that. Let's just order a movie and KMC til we pass out :)
