Pain in the bum
Pain in the bum is when someone’s butt is so irritating, it’s like it’s been dipped in hot lava. It’s a British way of saying someone’s butt is really annoying, and it’s been around longer than your grandpa.
My brother is pain in the bum for eating all the cookies.
My teacher is pain in the bum for giving me extra homework.
My dog is pain in the bum for barking at the mailman.
