The "he dead" reaction grew out of gaming and sports commentary culture, where a flat, understated call after a violent hit became funnier than an exaggerated scream.

Because the line states the obvious with total certainty, it pairs with almost any clip of a sudden defeat, which is why it remains a staple alongside other blunt reaction sounds in short-form video.
