What does the word ICYMI mean?

According to Cyber Definitions, the best resource for internet slang terms, the meaning of ICYMI is “in case you missed it.” This term is used to give someone information in case they are unaware of it. Someone might use this term on a social network such as Snapchat, Instagram, or Facebook, or in a text message. This new abbreviation can be used on all kinds of social media. It is often used in headlines for concision or when there is a character limit such as on Twitter. A news source might tweet out a link to a new story with the caption ICYMI followed by the title for brevity. This slang word is even used by journalists in the word today for the aforementioned example of widespread news on social media. Someone could also use this to talk about old content or topics to make sure their followers see it. While this is used in special situations for the proliferation of important news, the popularity of this term is very casual. If you used it in any other situation besides social media or texting, it could be considered negative and informal.

This is considered an initialism. An initialism is when each letter is pronounced individually – i.e. Eye See Why Em Eye rather than icky-mee – but in the case of “in case you missed it,” “Eye See Why Em Eye” is harder to say than the full form of the phrase. This term is great for efficient, concise writing but not speech. This term is also considered an adverb of condition. This will often be followed by a comma in formal speech, but not on social media or in text messaging.
