Definition:
"Out of the loop" is a slang term that means to not be informed or included in a particular situation or group of people.
Use case:
You can use this slang when you want to express that you are not aware of something or have not been included in a conversation, decision, or activity. For example, if your colleagues are discussing a new project and you have no idea what they are talking about because you were not invited to the meeting, you can say "Sorry, I'm out of the loop on this one."
• I can't believe you haven't heard about the new project, were you out of the loop?
• I've been so busy with work that I feel out of the loop with my own family's news.
• If you don't attend the meetings, you will always be out of the loop.
• I feel out of the loop when my friends talk about their inside jokes.
• Sorry, I'm out of the loop. Can you fill me in on what happened?
• After taking a month-long vacation, I realized I was out of the loop with the office gossip.
