Bustin' your lips
When you are jokingly giving a girl a hard time. It's like when your busting your friends balls over something, but since it's a girl your busting her lips instead.
Hey honey you need to relax a bit, I'm just bustin' your lips. Take it down a notch and go cook me dinner and iron my shirt. And while you're up, be a doll and grab me a cold one from the fridge.
