@mr_engineer A girl will almost never call you creepy unless you do something quite socially wrong. The problem is you lack social calibration and awareness. Which only comes from massive experience.
Dude, I've been there, I've done creepy. I know how it works. Girls never call me creepy any more. Because I know what not to say and not to do.

When you call someone this word, you're essentially saying that they don't deserve love, that they're unlovable. It's akin to the N-word for Black people, it's a sexist slur. 
My request to the mods is to recognize it as such and to regulate the forum for this anti-male sexism.
