It's sooo Hot out here...
Always. That's what makes the game more fun. Here's some of the things I've heard:
Khorne: BLOOD FOR THE BLOOD GOD!
Nurgle: IT'S NOT LUPUS!
Tzeentch: Don't forget your CHANGE!
Slaanesh: Make love not war!
etc etc. Sometimes it's lame, but that's what makes it funny.
Khorne: "I will consume you like a clearance sale at WALMART!!"
