Look at that face. Girl means business. She's got gold in her mouth, and more than likely a good amount of purple drank in her system, and she is intent on being the most "video girl" video girl she can possibly be.
Luckily for her, us, and especially A$AP Rocky, she succeeds. Dude made quite a bit of money from this video (and Peso, I suppose, but that video doesn't have crazy, crunk bling girl in it). The least he could do is give her a matching set for the chompers on the upper half.
Congratulations, crazy Purple Swag bling girl, you made watching that video about 50 times more enjoyable, you are truly a Hero of Music.
