The origin of this clip is unclear, as it was uploaded to a fan soundboard with no credits, but the name points to Gillberg, the WWE character created as a parody of WCW star Goldberg. Clips tagged by wrestling fans, under names like mmamarks, circulate on meme soundboards picked up for edits and reaction videos. Because the sound is only about a second and a half long, it works as a hype sting, closer in spirit to an air horn or a boom than to a spoken line, which explains why editors keep reusing it for hype moments and punchlines.
