The line comes from Chad Warden, a loud and deliberately over-the-top internet rant character whose clips have long circulated on soundboards and in reaction videos. His style mixes aggressive confidence with absurd complaints, and this particular insult stuck because it is short, quotable and easy to drop into almost any argument. As short-form video grew, creators reused it to mock know-it-alls, show-offs and bad takes, keeping the audio alive well beyond its original rant. Its appeal is its attitude rather than any single video context.

Chad Warden delivers the sarcastic line they think they smart and shit in this meme sound effect, used to mock someone showing off or acting clever.
This short clip captures Chad Warden mid-rant, delivering the line about people who think they are smart with a mocking, fed-up tone that lands instantly. His voice is loud, exaggerated and dripping with sarcasm, turning a simple insult into a punchline that feels both confrontational and funny. The delivery is fast and emphatic, with the final swear word giving it a blunt, unfiltered edge. Listeners immediately recognise the attitude behind it, which is why it works so well as a reaction: it calls out arrogance without needing any explanation, and it makes a moment feel sharper, funnier and more dramatic in just a few seconds.
