Ay mi pendejo circulates online mainly as a short TikTok and social video sound, where the Spanish phrase is recognised even by viewers who do not speak the language. Its appeal comes from the contrast between the blunt wording and the light, musical delivery, which keeps the moment funny rather than hostile. Because the clip is only about five seconds long, it slots easily into reaction edits, duets and short memes. Creators keep returning to it for gentle teasing, especially when a clip shows someone making an obvious, harmless mistake.
