To be a cynical asshole. Mainly thinking of everything as "shit" or "shitty" even if only a little bit of that thing was shown. It also means to insult anyone that disagrees with you. Even if the person was being very respectful about it.
Basically a troll.

Cynicism; (noun); Derived from the Greek word for dog, it first described a current of Ancient Greek philosophy. The cynic ringleader Diogenes of Sinope was described as "Socrates gone mad". The cynics pursued The Good without minding any other values. This meant they could jerk of at dinner tables, shit in public and live in barrells. Diogenes was said to live '"like a dog", hence the name, cynicism.
Nowadays, cynicism means an attitude in life that is conscious about morally bad or evil acts, but makes a joke out of them or commits them anyway. The cynic is blasé, he thinks everything is stupid or redundant and tends to sigh a lot.
Cynicism is said to be linked to hypocrisy. The hypocrite wants to convince other people of the fact that he is doing the right thing, whereas he knows he is not. The cynic doesn't want to convince anybody. He is honest to the extreme. His friends tend to describe him as dark, evil, terribly offensive or hilariously funny.
