The 'Thanos Beatbox' meme stems from the 'Cartoon Beatbox Battles' YouTube series created by Verbalase, specifically the episode featuring Thanos vs. Darkseid. The clip of Thanos performing a high-energy beatbox routine became a viral sensation across TikTok and YouTube, often paired with the lyrics 'Let me show you how to scratch it.' It is widely used in shitposting culture and irony-laden videos, where Thanos's intense animation and the catchy, rhythmic sounds are applied to absurd situations or used as a triumphant reaction to a minor victory.
