Actually Sunny it is YOU that has recently come up with a term that tickles my fancy - 'Twerp'
I hadn't heard that term used for years mate, very old school but quite amusing, and it is also a much nicer term than what the youth of today let fly from their potty mouths, not to mention myself on rare occasions.
So I am thinking that the following is what I shall use for a week or so, just to test the waters;
Director Aviation Safety - Twerp 1
Assistant Director Aviation Safety - Twerp 2
Associate Director Aviation Safety - Twerp 3
"Aviation, what aviation?"
