SAS, my definitions in the context they were used:
CHEST BEATING
Making technical statements just to prove ones own knowledge - I am guilty of this too.
ARSE
The pointless nature of the content. Not the man saying it!
(as in........a load of arse!) - My wife reckons I spout a lot of this.
I really hope you did not think I was calling JD an Arse!! If my grammar led you to think that then of course I will apologise immediatley to you and JD.
I hope we have cleared that up!!
