O.B.A.T.T.
O. B. A. T. T. means your boys are so fat they could start a new sport: sitting and eating.
My cousin’s so thicc, he started a new sport called ‘sit and eat’ and won the championship.
My boy’s so chunky, he doesn’t need a chair. He just sits on the floor and eats.
My friend’s so big, he could take a nap and eat a whole cake at the same time.
