The exact recording source for this clip is not documented, but the phrase combines jaja, the written Spanish form of hahaha, with c mamo, a shortened spelling of se mamó, slang used in Mexico and online Spanish-speaking communities when someone exaggerates or overdoes something. Short laugh reactions like this spread through WhatsApp groups, TikTok edits and meme soundboards because they are easy to drop into chats and videos without translation. It remains popular as a quick, recognisable way to call out an over-the-top moment in a friendly, teasing way.
