This clip is widely circulated online under the name Big Thor, but the exact original upload source is not clear from the title alone. It is mainly used in meme edits built around Thor, especially exaggerated size jokes, sudden zooms and dramatic superhero reveals. The format spread through short-form video reposts and soundboard sharing, where recognizable character-based audio labels help users find a reaction sound quickly. It remains popular because Thor is instantly recognizable and the joke lands fast in very short edits.
