First of all it's a dislocated shoulder. Second, it popped out very easily. Many people have a condition where their shoulder will come out of the socket if they lift their arms up. Mccain has this now after being hung up by his arms in vietnam, but some people are born this way. The ease with which her arm popped makes me think she has this. Furthermore, the angle that her arm is positioned in doesn't matter. What is the angle? The angle of someone losing an arm wrestling match. THis is unnatural, but not THAT unnatural. Worse case scenario is that she tore her rotator cuff, the one in front not he one in back, though that is still an awful injury. Not saying it's fake, saying don't dismiss the possibility that this girl can pop her shoulder in and out, I knew a kid who could do this in HS and would fuck with people all the time. Just saying, THINK about it.
