The 'Bombastic Side Eye' meme originated from a viral TikTok audio where a voice rhythmically narrates a look of intense judgment, escalating from 'Bombastic side eye' to 'Criminal offensive side eye.' The original sound was popularized by TikTok user @casa_di_pau in early 2023 and quickly became the universal soundtrack for calling out weird, suspicious, or socially awkward behavior. It is frequently paired with videos of pets, celebrities, or the creator themselves giving a sharp, judgmental glance toward the camera. Beyond just a sound, the phrase has entered the modern digital lexicon as a shorthand for expressing disbelief or disapproval in a humorous, sassy way.
