Boo thang 

Someone you have an unofficial relationship with. You could be "talking" to them, you don't call them your friend, and you don't call them your boyfriend/girlfriend, you call them your "boo thang". Pretty much someone you care about/love/have feelings for.

Friend: What's the relationship status between you and him? I heard you guys were dating.
You: No, not yet. He's still my boo thang.
