look up any word, like fluffer:
When you're talking to two people online and the same topic comes up in both conversations at the same time, completely unplanned by you.
Chat 1: I went to the beach today, I was so scared when I saw the 'Beware of Sharks' sign!
Chat 2: I just watched Jaws, best movie ever!
You: Major Conversation Sync.
