This sound is best understood as a generic automatic gunfire effect rather than a quote or character audio clip. On soundboards and short-form video edits, machine gun sounds stay popular because they instantly signal chaos, combat, and exaggerated power. Creators use them in gaming montages, reaction memes, and parody action scenes where realism matters less than timing and impact. Similar high-impact effects such as Pew_Pew and Metal pipe clang are often used for the same reason: they create a strong audiovisual punch in just a second or two.
