a stinky
A girlfriend so amazing she makes your life better, but also might make you cry when she leaves.
My girlfriend is a stinky. She makes my life better, and I can't live without her.
My ex was a stinky. She was amazing, but she left me for a guy who farts in public.
My best friend's girlfriend is a stinky. She's the best, and she even loves my weird hobbies.
