It's douche bag + boy friend.

Like guys on the MTV show, "She Really Going Out with Him."
Rebecca: "What's up?"

Hannah: "I'm talking to Blake! <3"

Rebecca: "Ew! Do you like him? He's such a diva and a

douche bag!"

Hannah: "Dude! He's my bf!"

Rebecca: "Well I hate him, so I'm not gonna deal with you right now. You can go have fun with your dbbf now, bye."
