play another game

Most people probably take the opportunity to sit and camp in a corner.  Me, I'll pull out the riot class and have fun watching people's reactions.

Was playing yesterday with a total noob, he was prestige 1 level 50 or something.  He was dominating people with his Riot shield.  It was hilariuos, going like 15-13 in HC KC.  I started running with him, both of us with our shields.  The reactions from the enemy team was priceless!! 

Thinking of doing it more, though I tend to always go negative with it...

I play mostly KC.  When hit detection/lag are an issue I backout; but if the other team is just owning us because they are good, I'll go suicidal and grab as many tags as I can so that I at least come out of the game with some points.  It doesn't hurt to panic knife a few people along the way.

I try not to rage quit and tough it out til the end of the game.

I usually rush like a mad man. If things are going badly I usually try changing classes and slow things down alot. I don't mean camp but maybe "patrol" a more defensible area.  I always try to come out of my games at least breaking even with a 1.0 KDR.

I drink a few beers. 

dashboard at the end of the game and blame it on lag or being the host......because thats what everyone does apparently.

go and play super meat boy, find out what real rage is and return to COD

cook a handgranade whilst jumping off something high,the kill cam will make you laugh and that should take your mind off it when,things dont go your way.

Turn your mic on and start laughing every time a teammate dies. You'll be surprised how many others will turn on their mics to give you a piece of their mind.
