This is from the Terry Pratchett book I'm currently reading. The people are Archchancellor Ridcully and his posse of wizards:
'It was just a thought,' said Ridcully. 'Come on, let's have a look at the rest of those heaps.'
'Yeah!' said the Dean, now in the grip of a wild, unwizardly machismo. 'We're mean! Yeah! Are we mean?'
The Archchancellor raised his eyebrows, and then turned to the rest of the wizards.
we mean?' he said.
'Er. I'm feeling reasonably
mean,' said the Lecturer in Recent Runes.
'I'm definately very mean, I think,' said the Bursar. 'It's having no boots that does it.' he added.
'I'll be mean if everyone else is,' said the Senior Wrangler.
The Archchancellor turned back to the Dean.
'Yes,' he said, 'it appears that we are all mean,'
'Yo!' said the Dean.
'Yo what?' said Ridcully.
'It's not a yo what, it's just a yo,' said the Senior Wrangler, behind him. 'It's a general street greeting and affirmative with convival military ingroup and masculine bonding-ritual overtones.'
'What? What? Like "jolly good"?' said Ridcully.
' I suppose
so,' said the Senior Wrangler, reluctantly.
Ridcully was pleased. Ankh-Morpork had never offered very good prospects for hunting. He'd never thought it was possible to have so much fun in his own university.
'Right,' he said. 'Let's get those heaps!'
Ridcully sighed. 'Bursar?'
' Just try
to understand, all right?'
