Jaboogle
A human who thinks they’re smart but just talks nonsense
My brother is a jaboogle. He says he’s smart because he knows the alphabet backwards.
That guy on the bus is a jaboogle. He talks about ‘the matrix’ like it’s real and eats a sandwich at the same time.
My neighbor is a jaboogle. He thinks he’s a scientist because he once mixed soap and water and called it ‘the ultimate experiment’.
