a sphincter says what

You tell your friend, 'You're so fat, you're a walking lunchbox.' He says 'what?' and you laugh like he just failed a math test.

You snap at your mom, 'You’re old enough to be my grandma.' She says 'what?' and you cackle like you won the lottery.

You tell your crush, 'You’re so ugly, you make the moon look bad.' They yell 'what?' and you laugh like you just saw a cat eat a sock.

You whisper, 'You're so dumb, you think pizza is a vegetable.' They say 'what?' and you call them a butt-hole like you’re the king of insults.

You say, 'You're so short, you're a step behind the rest of the world.' They go 'what?' and you act like you just taught them a life lesson.

You tell your little brother, 'You’re so weak, you can’t even hold a spoon.' He says 'what?' and you laugh like you just won a fight.
