The phrase would not happen to me tho is a piece of casual internet slang used to claim immunity from someone else's bad luck, and as a sound it works because the wording is short, quotable and easy to drop into an edit. It circulates mainly as a reaction clip in short-form videos, where creators pair it with fails, awkward moments and ironic reversals rather than with any single show or scene. Its staying power comes from that flexibility, since almost any embarrassing moment can be framed as something the poster claims they would avoid.
