Mr. C. M. Cockblock 

defining a cockblocker with a pseudonym when not able to directly state said cockblocker's name.

Very useful when the cockblocker is in close vicinity of you and/or partner. Also very useful as a label to said cockblocker

Girl: What's wrong baby?
Boy: I don't want to say right now ok?
Girl's Dad: Are you sure son? You do seem a little tense and uptight

Sinister look in Dad's eyes
Boy: Well, i would be more relaxed, but once again Mr. C. M. Cockblock strikes again (winks at girlfriend without Dad noticing)
Girl's Dad: Laugh out loud (he's too douchey to write lol)

mr.mystery 

A very mysterious boy who never tells a secret. He also keeps a lot of secrets about his friends and his family. But instead of that, he is very talented and a funny guy who can tell a scary story that will give you nightmares forever. Also if he is your friend, he will always have your back no matter what . On the other hand, if he is your enemy, he will make you regret anything you have ever done to him. Or if you do something to make him mad like take or break his stuff, he will hate you for a long time, ( a whole month.). But he can be mean when he wants to.

Mr.Mystery is very mysterious.
