Used by players of the MMO Wizard101. PEACE is for bringing peace to The Spiral (W101 virtual world). LOOT = Stuff you win in-game which you then immediately sell for in-game currency. XP = Experience Points, which are needed to level up. Widespread use as a battle cry, greeting, goodbye, or as equivalent to "Live Long and Prosper" or "May The Force Be With You."
It's time to defeat Malistaire. PLOX!
Time to stop playing and get back to stuff IRL. PLOX!
I'm heading into The Spiral. PLOX!
