A major oversight or obvious err in judgement or planning. As in the movie National Lampoon's Vacation, the Griswold family drives cross-country to Wally World theme park to find that it was closed. Or, failing to see an obvious easier route, short-cut, shorter line or less crowded approach to anything while preoccupied following the masses. "Stupid tourist, sheep, rookie mistake".
After spending nearly an hour looking for parking, Ves realized his Griswold mistake of shopping at the mall on the weekend.

Usually a white kid with a jew-fro, most of the time an ignorant asshole when around girls. Talks very little, and always very awkward. Also, he is usually into the gayest sport in the world; baseball.. ALso he wears shorts too small for him.
