The first meme of 2018 has been born — and it’s all thanks to rock star John Mayer.

His “Kylo Ren Challenge” caught on like fire after he dared the denizens of Instagram to lose their shirts to channel Adam Driver’s bare-chested bravado in Star Wars: The Last Jedi.

All you need is a pair of (particularly high-waisted) black pants and some nerve.

You can see the astonishing results by following the hashtag.

Here are some highlights so far:
