'Skir' is a long-running onomatopoeia in hip-hop and car culture for the sound of tires screeching, popularized as an ad-lib in trap music and drifting videos. On TikTok the triple repetition became a compact meme cue, detached from any single song or creator, used to punctuate fast movement or a stylish exit. Its appeal comes from instant recognition: even without a car on screen, listeners picture a sharp turn. The clip circulates mainly as a short reaction-style sound for edits.
