A girl in my class literally lost it because she wasn’t paying attention

A girl in my class totally lost her cool today because she wasn’t paying attention during our basketball unit in gym class. We were in a scrimmage, and after the other team scored, it was our turn to have the ball. My friend C was holding the ball and tried to pass it to another girl, L, who wasn’t focused. Before I could react, the ball hit L in the back of the head—not hard, but not super soft either. L freaked out and accused C of doing it on purpose, even though C immediately apologized.

Thankfully, Mr. P didn’t get upset with C and just told L to head to the locker rooms. A couple of minutes later, I went in to change, and we could all hear L shouting things like “I’m gonna beat that [expletive]” and “I’m gonna slap that ugly little [expletive].” It was quite the scene. I comforted C and decided to let Mr. P know what L was saying. When I went back to check on C, L was chatting with her friend M and was still going off, saying things like “I’ll let that [expletive] walk for now” and “ugly [expletive].”

I turned around and told L to chill out, and she completely lost it again, yelling something like “Calm down?! I’ll fight you, you ugly [expletive]!” That’s when Mr. P really lost it, screaming at L to “get the [expletive] out of my class” and that he “didn’t want to see her in class again.”

EDIT: To clarify, when I said “the ball hit her head,” it was a super soft toss—barely even noticeable. C definitely didn’t throw it hard or anything.
