"Empty message" is a trick discovered by Coderman51 that allows you to send an empty message on Discord. It is patented by him (like how mat has patented bh) so anyone else who uses it must pay him (send one unripe potato and a partridge in a pear tree to 1600 Pennsylvania Avenue [totally not the address of the president of murica or anything {Coderman == President???}]).

To send an empty message, you just need to type two space-separated underscores: " ". There are other methods, though this is the easiest one with a standard keyboard.
