After further investigation it would appear the main girl trying to calm Perry down and the one Mike Perry was saying "You aren't on my side bitch!" is Latory's (Mikes gf) cousin, Hadleigh. Below is Hadleigh (girl on right), people are already even beginning to joke about the video in the comment section. In the video (at approximately 00:23 seconds) you hear a guy say "Touch her again motherfucker" as Perry is arguing with the girl. At around 00:35 seconds you hear Hadleigh say "You were hitting my fucking cousin" most likely referring to Latory. Also take into account that Mike Perry has a history of domestic violence. Initially after the "You were hitting my cousin" comment I thought they were both referring to a male but it turns out they were referring to the random dude behind her that was apparently trying to calm down Mike down for hitting the "cousin" that Hadleigh is referring to (Listen closely from 00:30-00:40), it sounds weird because Mike refuses to address that part at all, he only wants to talk about the fact that he was "touched" by random dude in an attempt to be calmed down. It would also explain why his gf left the scene so early as she was probably already upset with him about something and knew it was only going to get worse.
