Martyrnoob 

A person playing on Call of Duty 4 online who uses the Martyrdom perk where a live grenade is dropped after you are killed, it is intended to catch your opponent off guard who thinks he is free and clear now that your dead. Its a noobs way to get kills even though he's dead. People who use this lack a real ability to kill people themselves and use this to level up.

I heard him coming up the stairs, knifed him and went back to sniping when i heard the grenade drop! he had martyrnoob on there was no way i could get out of the room in time!

MajorNoobOwnage 

The act of Majorly Owning Noobs, or MNO. MajorNoobOwnage only can occur when a professional gamer who is above MLG status gets matched up with people who have never been played before, and thus it is only an extreme condition which can only be performed by a pro.

1. "Dude, there's this guy named MajorNoobOwnage in our game... we're about to be MajorNoobOwn'd."

2. "Crap we're matched up against a pro, prepare for the MajorNoobOwnage."
