Nakosi
Nakosi looks good, can make you laugh, and is smart, but he's got a huge ego and thinks he's the only one who's ever been smart. He's like a brain who can't spell 'brain'.
He said he knew everything, then spelled 'smart' wrong.
He told a joke, then laughed at it and said mine was bad.
He said he could win any contest, then lost to my sister in a math quiz.
