It's called withdrawn.

I think you mean "withdrawl"? I never knew swearing (or not swearing) could do that to people...

It can't. In his case it's called "poor word management".

It just comes out of my mouth, okay? It's completely normal.

In that particular post, it's unnecessary and seems out of place. So it's hard to tell the difference between "anger" and "adding emphasis". But either way, it just sounds plain stupid.

I used to think it was normal to curse a lot, too (around the time I was still listening to Snoop Dogg). But then I turned 14.

I am 14. And yes, it's completely normal to swear.

Swearing's for the weak when they can't think of a proper response

I see periods are for the weak also. Writing too.

I believe swearing is fine so long as it's used responsibly and adequately. If you fucking say fuck every other fucking word you sound fucking retarded GODDAMNIT. They're like any other words in the English language, and like other words, you just have to master their usage so you don't sound stupid or naive.

Exactly. And the way that Oliveira is doing it is the type that sounds stupid and immature.

We have plenty of contributors on this site who are your age. You, however, stand out when it comes to swearing. Even if these kids swear a lot in real life, they don't do it as often - or sound as bad doing it - as you do on IMFDB.
