Americans are a mixed bag for me I love beating them but I hate losing to them.
I have rarely had a game where I have played decent Americans. I'm not saying it never happens, sometimes I do get a good bunch.
Most of the time its very bad trash talk and BS. Not funny trash talk or competitive one liners just ******** backchat.
You lose to them and they tell you that you are the worst players ever and should give up playing (what does that say about the people I beat in the last game?) I've lost games where I have had the highest score, the lowest deaths the highest accuracy, the most medals, and the longest killing spree, and they won by a single point. I mean FFS they can hardly say I suck when I pwned them, unfortunately for me my team mates were just not up to the task. Anyone with an ounce of common sence and sportsmanship would say "Good Game, XYZ you did really well, shame your team couldn't keep up." or words to that effect.
But what really makes me think WTF

is when we beat them and they start shouting "YOU SUCK!!!, you bunch of HOMOS" I just think WTF is wrong with you, we just beat you and your telling me we suck?
I also like the "You were lucky we could have taken you!" Yeah right you could have taken us if you had another 21 points.
I admit, however I can be quite bad with in game smack talk (and temper tantrums). But ant the end of the game as long as I'm not playing against a bunch of arsehats, I'll say Good game, win or lose.
