What is peace out meaning?

"Peace out" is a slang phrase used to bid farewell or say goodbye. The origin of the phrase is believed to be from the phrase "peace be with you," which is used as a blessing in many cultures. It became popular in the 1960s as a part of the hippie counterculture movement and has since been commonly used in various forms of modern street vernacular. It is often accompanied by a hand gesture where the sign of peace or victory is made by forming a V with the index and middle fingers with the palm facing outward. The phrase is now widely used in popular culture and social media as a casual way to say goodbye.
