Oh! Remembered another one!
Chargen. "Care-jen". It's short for character generation.
I started using it for the Traveller rpg (not unlike using "nish" for Inititiave, except it caught on in the Traveller community).
HA! I say Char Jen at first and was wondering who was Jen and what she did to get charred?!
"Aunt May's Discretion"
A bit of background. In Champions, there is a stat called Recovery. It governs how often you get back Stun points among other things. Being reduced to negative Stun means you don't get that recovery every phase; it might be once a turn, once a minute, whatever.
The last line is -30, which reads 'GM's Discretion'.
I was running a Champions game set in the Marvel Universe. We started having characters knocked unconsious into the -40, -60, even -80 range from combined attacks, etc
