Rocky is one of the original contestants in Battle for Dream Island, the animated web series created by Jacknjellify that began in 2010, and he returned in later seasons Battle for BFDI and The Power of Two. Because the character is mostly silent, his repeated bleh vomit gag became a defining trait shared by fans in edits, soundboards and compilations. The splat and squish version isolates that moment, making it easy to reuse outside the show as a short gross out reaction for cartoons, games and meme videos posted online today.
