Yeet began as playful internet slang in the mid-2010s for throwing something with force or celebrating a sudden move, and the word quickly became a shout in its own right. Short clips of people yelling it while tossing objects, jumping or dancing spread across Vine, YouTube and later TikTok, where it became shorthand for an exaggerated launch. Because the word is short, loud and instantly recognisable, creators still use it to punctuate throws, fails and exits without needing any explanation.
