Yeet grew from mid 2010s internet slang for throwing something with force and no care for where it lands, and it quickly became shorthand in memes for launching people and objects off screen. I'mma yeet myself flips that idea inward, making it a joke about removing yourself after a fail, an awkward moment, or a bad decision. The phrase spread through short form video, gaming edits, and soundboards because it works without context, pairs easily with falls and exits, and gives creators a clean audio punchline for self deprecating humor.
