There are also lots of game abbreviations that people use:
wd = well done
wp = well played
bj = bien joué (French: well played)
bp = bonne partie (I'm not sure exactly what this means, but it seems to be something like "have a good game," because it is said at the start of the game)
I've found it all very interesting, because I like language and its usage. I notice that the French people all use "lol," though, so that seems to have spanned languages. Sometimes I sit in the game's lobby and just eavesdrop on the French conversation, trying to make sense of a sentence here or there. It's all very interesting.
