Joe Biden, the 46th president of the United States, is a frequent subject of political meme edits, and this version borrows the heavy boom that editors have used for years to mark a shocking moment. The boom style spread through short form video on Vine and later TikTok, where creators reused it far beyond its original context. Paired with Biden, it turns speeches, gaffes and reaction clips into a shared meme format that signals disbelief without needing any extra explanation from the editor.
