Snorlax was introduced in the first generation of Pokemon games in the 1990s and quickly became one of the series most recognisable characters, famous for sleeping in the middle of paths and eating huge amounts of food. Fans have used its name and image in memes for years, and short voice clips built around an exaggerated reaction to it circulated on soundboards and social edits. The OMG phrasing captures internet reaction culture, where a familiar character appearing unexpectedly is treated like a major event for comedic effect.
