Some who gets straight A's in school, but out of school they're a complete dumbass who thinks they know every thing but don't know shit because they're only school smart
Man that he's fuckin dumb! He say's he gets straight A's, but he shore doesn't know shit when he's trying to explain a part of someone else's conversation. He must be a Smart dumbass.
