As someone who hasn't even touched a fighting game, it's really been interesting learning about all these fighting game mechanics. If him kicking this dude's arm results in this dude's HP going to 0 and leading to his defeat, that'd be so absurdly funny lol.
I don't know the specific game, but I recall there's a fighting game with low kicks that would target the ankle/shin; they were
really hard to block and I think the only way to dodge them was to move backwards, since jump didn't exist yet, but the ring also had a finite distance, so if you got trapped in it, you were basically screwed.
It's basically the ultimate noob combo (because it's easy to do, hard to escape, and a cheap win) and pretty much every fighting game has a variation.
