kabaib
They're like a pair of socks. You never question why they go together. You just accept it and wear them to church.
My uncle and his wife are kabaib. They’ve been married for 50 years and still say I do.
My cousin and his girlfriend are kabaib. They’ve been dating for two weeks and already talk about moving in together.
My neighbor and his wife are kabaib. They argue about the TV remote but still make dinner for each other.
