naabbit
A naabbit is someone who has the guts of a saint and the ass of a demon. They're the ones who fall in love hard and stay loyal until they're dead or you're dead.
My ex is a naabbit. She loved me like I was her last meal, then left me for a guy who could cook.
My brother is a naabbit. He married my sister and still calls me 'kid' in front of her.
My boss is a naabbit. He loves his job and his family, but he still talks trash about me in meetings.
