Sorry if I missed any...

I normaly use the break to get a Beer out of the fridge  

I usually laugh... then there are times I say 'BS' or 'WTF' cause there was no humanly possible way that person did not die.  I mean, I only unloaded my entire ak clip into his butt.

LOL, WTF?? At which point I usually pull a Sam Kinison ( if that is the way you spell it ) and run out of the room screaming with my hands in the air..

TYPE:

Poo,
Bugger,
Nice one,
Note to self: Don't type in the middle of fire fights,

DO:

Roll a cigarette
Get a beer
Try and stop my eyes from bleeding
Work off the RSI from playing far to long
Have a poo - depending on spawn time

It depends on the situation... If it really was a nice shot, I say nice shot, if I was typing at that moment, I say "####, I was typing", if I had to reload while I was shooting, I say "stupid reload", if we are playing inf, I mostly say nothing, unless he's dead also, because otherwise he can't hear you ("he" is the person who killed me)

Generally, I say nothing, because I want to go on gaming

On teamspeak I let my mates know I've fallen.  I don't use the ingame chat.

i usually say "nice shot" but if my death was a result of my or my teammate's ignorance or stupid play i usually say "bloody ####" or something along the lines of a brit curse.

Sure people can hear you playing in inf, you just have to use the normal chat and not the team mode.
I usually say a nice and easy 'lol' or 'n1' and after that i'll have a pee,drink,smoke,food.....whatever fits in till the 'Move,Move,Move'-Call comes and i have to rush back to my computer,before someone of the other team gets through to the starting point.

I dont type anything but if i get killed over and over by same guy/girl i use to wonder what he/she does better than i can do.
Then i can spectate to follow him/her and learn more about to became a better player.

Nothing when I got killed by the nme, when I step on one of my own granades (sometimes it happens, I know....I suck ) I type "Oopsie" or "Oops". When I got killed by one of my team-members I useally say nothing, I also noticed that players don't always apologize like with other games (useally the total nOObs that can be found on the public-servers).
