I usually hear some funny things people say to each other while playing. i don't have time to list them all, but these are just a few examples:
-COD2
Mr. Pain having... not exactly a remarkable night, and dying way too often....
" Glove, you have made the worst mistake of your gaming career, you have poked the bear"
"Viperz, I have looked up your name in my History dictionary and it stands for bear poop"
" No Canadian, hell no!!! (after getting bashed), then he spawns and starts a sentence... "you will pay for that Canadian, you have..." but gets interrupted by another bash. A two minute laugh follows this one, he leaves the game , goes for a "dump", comes back and says ... "wow, now I feel a lot better" lol
COD4 Ace
Rat Camper going at HONEYIMHOME after getting killed:
"Oh, bull shit Honey, that was bs" (honey is laughing his ass off)
"Honey, no way, wtf" (honey is still laughing )
RatCamper is getting really mad and goes:
" HONEY... IM HOMO "
