1. Goodbye
2. (intransitive verb) to leave or retire
3. (transitive verb) to kill

Note: I only heard the third meaning recently, but I thought it was pretty funny so I've included it.
1. "Yeah, see you then, peace out."
2. "Yo I gotta peace out, I'm tired."
3. "I just peaced out that spider with my shoe."
