What does IYKYK stand for?

If you know you know

IYKYK stands for “If you know you know”. It’s a phrase that is often seen on social media, or in text messages. When someone uses IYKYK, they’re talking about a shared secret or inside joke that only certain people will understand.

Most of the time, you’ll see young people and especially teenagers using IYKYK. It’s a big hit on platforms like Instagram, Snapchat, Twitter, and TikTok. It really took off in 2019 and you’ll often see it tagged with a hashtag and followed by a picture or video.

People use IYKYK to give a shout-out to those who will understand a hidden message or joke. For instance, your buddy might post that he’s done with listening to Justin Bieber and add “iykyk”. This is his way of hinting to those in the know that Justin Bieber was his and his ex’s favorite artist.

But not always is IYKYK used in a positive way. Sometimes, it’s used to make others feel left out or clueless. Like if someone didn’t make it to an epic party or wasn’t around when a juicy piece of gossip was being shared, they might see a post with “iykyk”, making them feel out of the loop.
