Emotes are special commands you can use in chat to express yourself. They are also shortcut to say something without having to type the enter message. By this trick, you can create an empty private chat window with another chatter. The recipient will only see an empty chat window opened without any message being received.
This trick can be done using those emote commands, which do not work if the recipient's username is not written (/LAUGH). To do the trick, just open a private chat with someone or in room and write any of the emote commands.
