It states it in a hellza stupid and obnoxious way but the OP picture is basically right, a few martial arts even have special terminology for yelling while performing.

Why would you ever want to stop?

but yes, people who just yell without any self-awareness look like, well, this.

I did taekwondo as a kid for ~12 years, got a 2nd degree black belt, etc etc. and yeah it does hellza work, especially in sparring situations. The guy who owned the taekwondo club my class was affiliated with was this 8th degree black belt Korean guy who was in his 50s and terrifyingly ballza and occasionally he would fly out from the Maritimes to test some of us and he would always pick a few of us to spar with. When he would yell, it would totally throw you off. He'd come flying at you and let out this bark that would startle you so much it could throw off your balance and then he'd have you and just kick your ass.

It was incredibly awkward being an adolescent boy and having to yell like that though because of voice cracks. Once I was well into puberty and had settled into my lower voice better, it was fun to watch the 12-13 year old kids and listen to their uncomfortable voice breaks and accidental squeaks.
