I have seen boys and girls throwing tantrums but it's nothing like this dude describes.
I've seen girls baw their eyes out when failing a test or because she can't attend anymore for reasons and will miss her friends and that kinda stuff.
I've seen boys shout and punch a desk before fuming out of the classroom, or getting all douchebro when refusing to take out a hat and trying to OWN the teacher with facts of da hood.
That said, I've seen more boys and men go fucking berserker and/or hysterical. Every other day there were a bunch of guys having "fights to the death (not really)" at the school and specially high school exit, while girls fighting was very very rare, but when they go they fucking go. Yet somehow manage to not get any lasting damage, boys usually went home with a bloody nose and/or with a black eye and........why yes my little corner of the world was a bit barbaric, thanks for noticing.
Ahem, anyway, with those things in mind, I've never seen a boy doing what this one describes. Keep in mind this is his version of events, who knows what he actually did and what he's not telling. We know how troons love to spin a story. Story goes spinny.
Seeing how there are very specific negations like "people can't tell when I cry" he was probably sobbing and doing weird noises and nobody dared to say a thing because even bullies know when shit's fucked up.
