The 'Hand Me the Aux Cord' meme, also known as 'You Better Not Play Trash,' rose to internet fame in the mid-2010s across Twitter and Tumblr. It humorously captures the high-pressure social situation of being responsible for the music during a car ride. The meme typically follows a format where someone requests the aux cord, promises to play something good, and is then depicted causing a literal explosion, fire, or cosmic event due to the 'heat' of the track. It has evolved into a versatile template used by music fans of all genres to celebrate their favorite artists or poke fun at their friends' questionable tastes in music.
