The Full Form of IFKR is‍ I fucking know right.

While some of the phrases used in text speak originated in that medium, others, like ikr, are adopted from everyday life.

It’s complete agreement in what is being said.

Ikr is an abbreviation for the phrase “I know, right.” The phrase first appeared during the early 1990s, and its first uses in electronic communication can be traced back to at least 2004.

The phrase itself has been a pet peeve for some language commentators. The phrase “I know,” on its own, signals that we are aware of something another person is saying, or that we agree with it. According to some critics, adding the word “right” turns the phrase into a question. However, the “right” in “I know, right” is actually just a way of adding emphasis. Using “isn’t it” instead of “right” can also work in a similar way.
