It's dynamite! ...Beyond that, I don't have a clue.

You're thinking of 'TNT', which actually isn't the same as dynamite at all, a common confusion that isn't helped by depictions of explosives in cartoons and games freely mixing up the two.
Another user answered the meaning behind 'TMT' here.

I'll never understand Japanese (or maybe it's just anime trope) obsession with "high-school memories", when these memories are just some most common activity. If anything such things are much better when you are like 20+. It's still youth but you are financially and personally independent.

Thing is, high school is where they get the most freedom considering japanese work culture, thats why high school is the default setting
