Someone who after doing copious amounts of cocaine becomes super paranoid and thinks that everyone is out to get them. Frequently happens to heavy users and retards. Sketchtardness is contagious and can be passed to others, thereby making it a buzzkill as well. If you see or are hanging out with a sketchtard slap them immediately, or distract them by doing karaoke to Vanilla Ice "Ice Ice baby..."
Tim: "Holy fuck is that a cop car?"
Jim: "No assfuck its a carola, stop being such a sketchtard and lets do another lizzle."

OR

Kim: "OMG i've been doing coke all day i feel like such a sketchtard"
