The act of using a sticky grenade to stick some one in halo3. Usually from a far distance away or killing more than one person with a single stick or "God Stick"
1. Dude, I just got a triple kill with one gernade, total God Stick.
2.I just threw my gernade in the air and God Stuck someone! ROFL
Not blasphemous enough to compare something you love to God himself? Then compare it to a piece of God on a stick! Not as good as God but close indeed!
"I just defeated the armies of Satan! That's totally God on a stick!"
