Ngl when flossie is pouring Olivia's first shot, you can tell Olivia so cbas with flossie (at least in that moment). She pours her a bigger shot than she wants and then takes the piss by saying ugh it's Sourz. I've had friends like flossie before and the small digs to make u feel embarrassed are the worst. Ofc they will all piss themselves laughing about that pretending it's so not true that they hate each other, just like how they take the piss about people saying they've changed but
if that's the vibes, that's the vibes.
