The phrase my son so dumb IQ 21 he try to make friends spread as a short meme audio on soundboards and social video edits, where the broken phrasing became the joke itself. Creators reuse the exact wording in captions and comments, which helped the clip stay searchable and recognizable even without a clear original source. It is now used less as a literal comment about a child and more as a generic roast for dumb moments, awkward introductions and failed attempts at being friendly online.
