Hmm..... If you say, I'll have to repeat myself though; this is discussion over the net, so it's hard to exactly prove much, so I'll leave it for you to have the last word here as well.Partly yes you are mistaken. And I will use dr. House to show my point.
The naturally sarcastic people, are just sarcastic. No skill , no imitating no nothing. I remember being like that since I was 10 or something. That's my character.
On the other hand, it has become quite a trend to be sassy and rude towards others. Some think they look like "badasses" or whatever when they mock somebody. Those watch House (or other characters like him) and masturbate to his lines, copy them and use them to show off. That's what you are saying and that's why you are partly correct. (instead of House one might imitate a real person but nowadays they tend to imitate what they see on TV/internet).
The copycats are usually pathetic asses with inferiority/superiority complexes who like to mock others in order to cover their own stupidity or the fact that they are themselves way weaker inside than they pretend to be.
(also, don't thank me for my time or anything, this is a forum and that's what we are supposed to do in it, discuss)
I do feel the need, you shared so much of yourself after all, actually I'm thankful to all whom chose to take this topic seriously!
You did chose my thread to post in after all, seriously nonetheless~
