The clip comes from *NSYNC’s 2000 hit “It’s Gonna Be Me,” specifically the vocal delivery by Justin Timberlake that listeners hear as “May.” It became a recurring internet meme as people shared it every year at the end of April and start of May. The joke spread widely across social media, image macros and short video edits because the timing is simple, recognizable and easy to reuse. Its staying power comes from that annual reset, turning one lyric into a dependable seasonal meme.
