If you talk by ignoring the reactions of the others, basically you'll be the definition of a creep (for me). Technically, a creep is (for me, again) often talking to himself/herself even when there is someone else(s) around like he/she doesn't want to accept people real existence around. Creeps are like they want people to be ghosts and don't want to see them as real people or something. Plus a creep is very anxious to the others so he's/she's socially awkward and he/she's very insecure. In addition to that, what distinguish creeps from other shy or introverts people is a highly fertile imagination based on sexual, agressive and/or glaucous pictures which are ignoring the outter reality, will be shocking or unacceptable by social groups if they were directly expressed and creeps WANT to express these phantasms directly even though they can't (that point is important cause it what's make the difference between creeps and others imaginative persons who are expressing things indirectly like artists)
That is the social definition of a creep as I see it.
But even if I knew you enough to call you a creep, I won't. It's a social classification and it's no more fashionable anyway.
However, you can be called a creep because you don't like to talk to people or if you talk to them like you're soliloquizing with inapprehensible monologue (like this one u_u).
Not saying you'll be one then, just telling you that people will see you as one.
What that too much ? I got carried away on that one...
