What does IYKYK mean?
IYKYK is an abbreviation of the phrase “if you know, you know.” It is often used as a way of acknowledging some common knowledge, or a shared experience.
Examples of IYKYK
One of the Nets' blockbuster signees of 2019 spent some of his Friday before the WNBA draft listening to Jay Electronica's "Universal Soldier." At least he was tweeting out the lyrics from the song. And many unfamiliar with the rapper assumed Kevin Durant was writing out his own lyrics. To which I say: IYKYK.
