Who says seniors are out of touch with technology? This (allegedly) 60 year old man plays Call of Duty : Modern Warfare 3 religiously, and he can hang with the best of them.
Anyone who has played competitive video games sometime in the past ten years knows that trash talking is a big part of the sport. You rub it in your opponents face when you're doing well, and swear like a sailor when you're getting your butt kicked. What we might call "bad sportsmanship" in sports, is the accepted norm when it comes to video games.
It may not be politically correct, but there is something irrefutably funny about watching this old guy cuss out a twelve year old. Enjoy.
