Lag Fighting
You’re fighting over messages and you’re too slow, so they keep talking about other stuff while you’re typing your message and you send it when the whole conversation has already moved on.
You send 'I’m still mad' after 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 they just left.
You send 'I’m not done yet' after they said 'I’m going to bed' and they ignored you.
