Pax

People may send "pax" in a message to convey peace and love (often when departing). The term comes from the Latin word for "peace" and the mythological Greek goddess (of the same name) for peace.

In messages, people often use pax to send good wishes to someone, often at the end of a conversation. For example, you may need to go to bed and end your online chat with a buddy, so you send, "I'm tired and gotta wake up early. TTYL. Pax." Or, you might be texting with a friend and need to get to work, "I'm running late. Pax."

Some people also use PAX as an acronym for "peace and love." In this case, the "X" stands for "love."
