The boys of One Direction
made one adorable fan's wish to meet them come true on Tuesday, hanging with him backstage at the band's concert in Kansas City, Missouri. But Gavin, whose sister Hannah tweeted got to meet the British boy band through the Make-a-Wish Foundation, also gave them something back -- a hilarious tutorial on how to "Whip/Nae Nae"
from Silento's summer hit "Watch Me (Whip/Nae/Nae)."
You know, the song you can never get out of your head.
According to Hannah, Harry Styles actually thought "Nae Nae" was mayonnaise.
Still, despite the initial confusion, the handsome boys eventually got it -- though Harry's clearly not a big dancer.
As a bonus, Gavin even got the boys to hilariously comment on Zayn Malik's departure. When Gavin mentions to the band off-camera that Zayn isn't there, Harry cries, "Don't remind us!"
Obviously, Gavin left an impression on the 1D boys. Niall Horan tweeted about meeting him on Wednesday, writing, "Last night we met a very brave little dude called Gavin. Gavin in an old head on young shoulders, so much fun teaching us how to whip."
Hannah, of course, posted Gavin's sweet reaction.
"I am so excited," Gavin says. "I want to say thank you to Niall, OK guys?"
Zayn recently threw some major shade at One Direction, tweeting that he left the band to make "#realmusic."
