pain in the mik'da
A thing or person who gives you headaches every single day. It’s like having a loud, smelly neighbor who also eats your lunch.
My mom is a pain in the mik'da. She yelled at me for eating cereal for dinner.
That annoying song was a pain in the mik'da. I had to listen to it all week.
My friend is a pain in the mik'da. He borrowed my pencil and never gave it back.
