The above video depicts a female student having a meltdown in the library at Cal State Northridge on Tuesday. Despite several reports to the contrary, the video was recorded and first posted to Facebook by a CSUN student named Ashley Monroe, who claimed in comments below it that the altercation began after the girl demanded others in the library "not breathe loud[ly]."
The video itself starts with another female student telling the girl to "calm her dramatic ass down," to which she responds by charging back at her and screaming, among other things, "It's finals right now!" Things went downhill from there: one witness called it "the most dramatic tantrum," and another claims it got "so much worse" after the video ended.
Hopefully she's calmed down by now.
