Peace-up means "peace". The "up" part is used because "peace-up" is usually followed by a city that's "down".
Peace-up, A-town down! - Usher from "YEAH!"
Peace-up, C-town down! - My homies
Peace-up, B-town down! - Jay-Z

A cool way of sayin goodbye to your homeboys or homegirls. Popularised by the song 'Yeah' by Usher, "Peace up A town."
