Hair Trigger Temper Questions

I guess I'm a little confused about this trope. Is this referring to a character who yells a lot to be a bully (the description almost sounds like they're doing it on purpose to be obnoxious), or could a character who simply gets angry really easily count as this trope? If not, is that a different trope?

This is kind of about the Berserk Button trope too, because what if a character has multiple Berserk Buttons, does it still count as that trope?

Hair-Trigger Temper was originally The Pesci based on Joe Pesci having a bit where he would snap at every little thing. It's the "every little thing" that makes Hair-Trigger Temper work. Any minor annoyance induces a frothing rage in the character, even if it's minor or completely made up.
