it means this is the internet. it is a free commmunication forum. it is not a standard prose lesson. most people understand that at the age of 12. do yourself a favour and learn to read or perhaps to think outside of the most basic english language expression. i recommend poetry and perhaps some stream of consciousness novels. at your level though, comic books might break you out of the latent pedantry and banality your diseased little mind is exhibiting.
It's kind of like a 12 year old discovered the thesaurus function on his dads computer. Your mindless swill of hypocritical insults are physically painful to read. The effect of said insults emotionally are gentle at best, but laughably pathetic.
Learn to write. Learn to read. Learn what irony means then cut yourself for being a silly billy.
Dammit, I bit.
