Lag Fighting
You’re fighting someone over messages and you’re too slow to type your reply, so they talk about something else and you send your message when they’re already on to the next topic.
You send 'I’m still mad' when they said 'I’m going to get pizza' and they just left.
You type 'I told you so' when they said 'I’m going to beat you up' and then they logged out.
You send 'I’m not done yet' when they said 'I’m going to bed' and they never replied.
