The 'It's Gonna Be May' meme features a close-up of Justin Timberlake during the *NSYNC music video for their 2000 hit single 'It's Gonna Be Me.' The joke stems from Timberlake’s specific vocal inflection, which makes the word 'me' sound distinctly like 'May.' This linguistic quirk was first noticed by fans on Tumblr around 2012 and quickly became an annual internet tradition. Every year on April 30th, social media feeds are flooded with this image to signal the arrival of the new month. It has become one of the most enduring seasonal memes, even receiving official nods from Justin Timberlake himself and the rest of the *NSYNC band members, cementing its place in pop culture history.
