2. Four letters on a QWERTY-keyboard that are in a convenient row, and are thus easy to type for the purpose of spamming, receiving attention or expressing anger.

Four of the most vulgar words in the english language (ass, shit, damn, and of course, fuck) merged together to create the god of vulgarity. This word is used only when it is extremely neccesary.

(side not: the conversation below never actually happened, and the person named "trip" does not have a speech impediment, forcing him to talk like a complete idiot, hes is, above all, generally normal, and would not say this)
Trip: Hey! d1d j00 sEe the NeW fInAl FANTASyyy VIDe0?

Ethan: wow. ASDF noob.

Trip: NoOoOoO000oOo!!!1

Ethan: What the hell is wrong with you? I told you to ASDF!

Trip: *owned*
