O'Brien
A way of talking that is silly and makes everything sound funny. You use it when you want to be the class clown.
My friend talked like an O'Brien. He said, 'I ate a sandwich.' I said, 'That’s not funny.' He said, 'It is, it is.'
My teacher talked like an O'Brien. He said, 'I am the best teacher.' I said, 'No, you’re the worst.'
My sister talked like an O'Brien. She said, 'I am going to the mall.' I said, 'You are the worst person in the world.'
