MMC
a group of dope ass, pong playin, show goin, gym shorts wearin, whoop yer ass if you step out of line type o' niggas. Most notably is their uncanny skill to sink pong balls into red solo cups and kick yer ass off the table so quick yer dick will turn inside out and grow a clit. Come to an MMC party and yer guaranteed to get drunk because youre guaranteed to get kicked off the pong table no matter how "good" you think you are. Started off as a Diablo clan, now Fayetteville legends, "We can do 1 on 1, but if you win... yer fucked."
