Jack's Mum
Jack's Mum is the best insult ever because it sounds smart but it's just a fancy way of saying your mum is a mess.
I called my brother's best friend 'Jack's Mum' and now he's my enemy.
My mom said 'Jack's Mum' to my dad and he threw a plate at her.
I told my friend's mom 'Jack's Mum' and she said I was the worst kid ever.
