Penis Music is an ironic catchphrase often used in GIF captions to humorously describe GIFs of various characters dancing. Originating from a meme posted on Tumblr in December 2019, and subsequently circulating in the /r/okbuddyretard subreddit and iFunny, the format achieved mainstream popularity on Twitter in February 2020. The meme later mutated to include other variations in the form of X Music snowclone.

The meme usually has the song Rubber Band by Jackal Queenston (or some kind of remix/mash up) accompanying the gif.
