The IYKYK full phrase is “If you know, you know.” When somebody uses this internet slang, it means that there is an inside joke. Most of the time, no explanation or additional context follows so it has a sense of exclusivity too. If you see it and don’t get the reference, you probably weren’t meant to, fair or unfair.

People often associate IYKYK with cliques or other select groups, but that’s not always the case. For example, fans of a baseball team might use the term in reference to an infamous play. Most people who are not into that team or who are not really into baseball won’t get it.

Examples:

  • This is beginning to feel like Homecoming 1988 all over again. IYKYK
  • The touchdown reception at the end reminded fans of “the Catch.” IYKYK
  • Guess who just did a Ronald? IYKYK
  • That was a respectable snowfall, but it had nothing on Snowmageddon, IYKYK
  • I can always tell a fellow climber by the kind of carabiner he uses for a key holder. IYKYK
  • Show up prepared or don’t show up at all. IYKYK
  • If you don’t know proper bear etiquette, stay out of bear country. IYKYK
  • If you have to ask, you shouldn’t be asking. #iykyk
  • At the funeral, there was a Big Lebowski moment. IYKYK
  • When I put iykyk and he asked what that meant, I lol’d and he got all offended.

Let’s answer that second question first. You’re under no obligation to explain your reference or give any more context. You can if you want to, and some say you should if you post it in public. But you don’t have to, and if you only want certain people to be in the know, that’s fine.

Now, let’s look at where to use it.
