look up any word, like eiffel tower:
A hacker can be your key to an instant promotion, or a humiliating defeat. They sometimes claim to be part of MLG. This may very well be true, but all that means is that hackers consider themselves professionals. If you're lucky enough to play a generous hacker, you could level up through 2 prestiges in one match.

The cunt that ruins every online game invented.
They tend to waste 90% of their time in their mom's basement finding ways to hack mw2 or gta4 ruining the fun for everyone rather than getting a girlfriend or just playing the game. Also, sometimes hacks websites or even bank accounts instead of getting a job. See Loser

Seen at the top of the technological heirarchy, a person fully capable of using a computer to the fullest extent, and knows at least three programming languages without having to refer back to a tutorial, and has done at least one recognizable thing with them.

Not to be confused with cracker. While a hacker may have the capacity to gain unauthorized access to a computer, he/she will only do it to expand the boundaries of knowledge and promote virtue, while a cracker will destroy the results of a hacker.

It is unorthodox to consider yourself to be a hacker, rather than be considered a hacker by other hackers.
