You're in a group chat, and everyone is talking about a meme you've never seen, but you say, 'I know that one!' even though you've never heard of it.

Your friend is telling you about their new job, but you just say, 'That sounds cool!' even though you don't know what they're talking about.

You're at a party, and everyone is laughing at a joke you didn't hear, but you still say, 'That's hilarious!' like you're in on the joke.
