Ace Nade
When you throw a grenade(in Call of Duty or any FPS) randomly into the air and you score a kill or two, you are required to shout "Its an ace nade!"
"dude how did you get 10 kills already!?!"
"oh dude it ain't nuthin.. i threw an ace nade and got a double kill"
"oh dude it ain't nuthin.. i threw an ace nade and got a double kill"
