Someone who'll believe anything written or seen on internet media - who lacks critical thinking skills and judgment when it comes to internet based sources. A gullible person who'll never double-check unverified internet provided information. A shebster will have a tendency to doubt intellectually superior sources and favor questionable, web-based, collaborative sources instead.
Duuuude I edited a wikipedia page to make him believe that Osama Bin Laden didn't die and was actually an alien from another galaxy that went back to his homeplanet...and he fell for it !! He's such a Shebster !
