PK is an abbreviation for "peacekeepers."

I'm a peacekeeper and YOU can be a peacekeeper too. <33

PKs are known for spreading the peace. Most of us PKers are also part of a widely known club called CIRCLE K INTERNATIONAL but that doesn't mean that you can't PK if you're not a CKI-er! EVERYONE can do the PK.

Just throw up a peace sign whenever you say "PK!"
If you a troublemaker, you can opt to throw up the PK whenever you are caught for getting into trouble. PK! (^^)-v
