There is no widely documented origin for Mason Lucky Pants, and it circulates mainly as a short soundboard clip shared among smaller creators rather than as a line from a famous film or show. Its appeal comes from the name itself, which is specific enough to feel like an inside joke while still working over almost any lucky or confident moment. Because it is short and easy to drop into an edit, it keeps getting reused in memes, gaming clips, and reaction videos where a quick, unexpected punchline does more work than a longer joke.
