She's being the Female Weezy lol... it's annoying how she does it on such public platforms though. It was cute in the behind the scenes of the YU Mad video but, really, in an interview?
She's channeling female weezy. Anytime she says 'da kid' she's speaking in Weezy's tongue. There's actually a whole video of her putting on that persona on youtube with dreads and all.
