Someone who claims to know something about anything but in reality is only a half-witted chronic masturbator who wishes to impress with their ever-so-lameass limited knowledge in a vain attempt to cover-up their double-digit IQ, usually resorting to Wikipedia in desperation.
Troll: "i know everything about quantum mechanics, evolutionary biology, general relativity, and medicine because I read it on Wikipedia".
Someone who is totally lame. You would rather watch paint dry than be in the company of such a person.Can't get any action unless they paid for it, and therefore, more than likely spend a great deal of time masturbating or "spanking" it. Can also be used in it's diminutive form "spank".
Don't tell Chad about the party, he's such a spanker. Or: I wouldn't give that spank the time of day!
