Where you or I might walk the few steps from the top of the cell stairs to the seat in the dock without conscious thought, this lad seemed to consider it an opportunity to make the most outlandishly exaggerated demonstration of what I supposed was "chill".
His entire vocabulary seemed to have come from American films as well. At on point he said to the prosecutor:-
"I ain't no jive ass turkey man!"
I took the opportunity afforded and asked him what a jive ass turkey was. He was completely taken aback and for a few seconds floundered and blustered until, with a flash of genius, he composed himself and said, in his best Barry White voice:
"It is what it is man"
You had to be there to appreciate in full the comedy but I hope this has given you an indication
It is just such a crying shame that the lad had so little self esteem that he felt the need to rely upon such a clichéd persona
