I just think there is quite a big difference in reasoning (unless he wanted to do something completely different) compared to the arena scene for example.
In the arena, he is actually doing a random-guy move by getting smashed by the main character.
The only reason he got any attention is because he wanted to show off how BAD he can get beaten up and that was mistaken for tenacity.
In this case however, he "sacrifices" himself with a loud scream, grabbing all the attention and the "goal" is that everyone will talk about what he did for that girl - it will for sure not be "Ugh... that was lame". And since he is most likely not planning on leaving the school, after this event he will be declared a hero.
All his moves so far were supposed to show how lame he is.
This move however seems to be about the complete opposite to me.
And isn't he trying to avoid "messing" with main-character type characters, so he doesn't become the focus? This will as well lead to the exact opposite direction (and not by accident, like all the other times).
