IYKYK means "If You Know, You Know." This abbreviation is typically used on social media and in text messaging to indicate that a message or the content being referred to has an inside joke or a hidden meaning that only a select group of people would understand. It suggests that the information is somewhat exclusive or understood only by those who are in the know or have shared a common experience. This is usually done without providing any further explanation. For example:

  • So that's where Jo's trousers got to! #IYKYK.
  • Never mind what day it is, what year is it?! #IYKYK.
IYKYK is the password to a clandestine club of understanding. It's exclusive, yet inclusive; cryptic, yet revealing.
