A guy with a first name starting with a "C", such as Christopher; and a last name beginning with "Mo" such as Morgan, or Morton.

This guy usually comes off as charming and a great dancer, but watch out. C-Mo's are wishy-washy snakes. If you date a C-Mo they will cheat on you then smile the next day and lie through their teeth. And since they are so handsome you will believe them. C-Mo's will sleep with your friends, do drugs, have a dark side, but will be able to hide it from everyone as they like to "look" good. Watch your back around these sneaky suckers.
Me: I'm dating C-Mo! He's so handsome!
Them: Oh watch your back. I saw him last week making out with Sarah, that skank.

Me: Oh I trust him he's so charming and loves me.

C-Mo: I slept with Sarah last night but I love you.
