A person who spends most of their pathetic life on the computer, spamming aimlessly on MSN, AIM, ICQ or some other chat program. They spend hours on end on it. But then when a simple task comes up like running a program, they have to ask you like a babbling idiot until you help them.
Even then they still seem to ask what you do even if you can't make it any clearer and you would have better luck explaining it to a deaf dog with herpes.
