If you're all worked up ATM, your friends may send you DMY ("don't mess yourself"). Literally, DMY means "don't poop and/or pee your pants."
In reality, however, DMY is just a prompt to calm down. Whether you're laughing too hard or you're a bit too angry, you may need to chillax if you've received DMY in a text or chat message.
