The exact origin of this clip is not documented, but it spread through gym and fitness edits online where lactic acid removal became shorthand for the burning stretch after intense training. Creators reused the yell as a standalone reaction, similar to other scream meme clips and the drawn-out FAAAH sound used for sudden pain. Its short length and clear peak make it easy to loop, layer and drop into TikTok, Reels and Shorts, which helped it stay in rotation for workout humor and overreacting to everyday discomfort long after the first posts.
