It means my “boyfriend” which is why Randy said it was weird to hear him sing it...I thought it mean “brother” as in black lingo and that was the reason. Well, we all learned a new word. ;)
Ya learn something new every day...
Just for the record, allow me to revise and extend my previous remark...
Me and Casper.... NOT an item!
No, it can mean girlfriend, boyfriend or anyone you choose to use it for an affectionate term.
