In Case You Missed It (ICYMI) is a phrase commonly used in social media, blogs, and news platforms to bring attention to information, events, or posts that the audience may have overlooked. ICYMI is often used as a preface to share or repost content that has already been circulated but remains relevant. For example, a news outlet might post an ICYMI update on an important story that developed earlier in the week. Gen Z uses ICYMI in casual conversations to highlight important messages or updates that friends or followers may have missed.
