Jaahid
A Jaahid is someone who sticks to your brain like gum on a shoe. They either make your life a nightmare or turn it into a party.
My ex is a Jaahid. I still hear her voice in my head when I eat cereal.
That teacher is a Jaahid. He made me cry in math class twice.
My cousin is a Jaahid. He turned my childhood into a wrestling match.
