The clip comes from the lifewithmark dog videos, where a pet uses recorded speech buttons to answer its owner. That setup made the stuttered refusal easy to clip and repost, and it spread across TikTok and meme pages as a standalone reaction. Viewers kept it because the timing works without context, similar to the oh my god bro oh hell nah man reaction. It is now used less as a pet video and more as a universal sound for saying no to something ridiculous or unwanted.
