Can we talk without chatting?

For some ridiculous reason of which I can not comprehend the boys in my year group have decided that instead of having a conversation like normal intelligent people we must "chat". "Good chat" is definded by the extent to which you can ridicule another person or generally badinage your current situation. If you have "smelly chat" then you are not considered one of the lads...ahh the maturity. After a Saturday night of the lads deciding to play DUDstep, pour beer all over their bodies including in their eyes and burn each others t-shirts I decided that it doesnt take a great amount of acuity to "chat". The "chat" vocab consists of:
Crust= Bad
Aids also= Bad
Hane= Cigarette
Mess= Self explanitory
and Key= Essential
The lads really enjoy "crust" and aids" as nothing is good enough so mostly things are negative.
So today I ask...May we talk and not chat?
