What is iykyk?

"IYKYK" stands for "If You Know, You Know." It is an internet slang acronym often used to indicate that a piece of information or an inside joke will only be understood by those who are aware of the context. The phrase is popular on social media platforms like Twitter, Instagram, and TikTok, where it might accompany posts, memes, or comments that resonate only with certain groups. The assumption is that if you're "in the know," you'll find the content relatable or amusing, while others may be left puzzled. "IYKYK" tends to create a sense of exclusivity or camaraderie among those who share the understanding.
