Actually, I wouldn't entirely disagree. Surrey is beautiful, but it has its drawbacks and a surplus of petty bourgeois people is one of them. Are you actually telling me that if you attended a Whitgift function of some kind you would use c*nt freely? At Charterhouse it would probably result in my son being expelled.
Well we obviously wouldn't say it in front of our teachers, but we'd certainly call them it behind their backs. Generally, among the boys and in social circles, it was pretty commonly used.
Granted, Whitgift - whatever its benefits - is still in Croydon and so probably has a somewhat rougher edge than Chartreuse, but even so I think you'd be surprised. Some of the sweariest men I've ever known have been public school boys.
I knew a chap who went to Sherborne and regularly started fights when drunk by sidling up to the girlfriend of (invariably) the biggest bloke in the bar and saying 'I'll bet you've got a lovely ****'*.
He was as posh as you like.
*Obviously reprehensible behaviour of which I wholeheartedly disapprove and which I certainly never found amusing in any way - oh, no! #MeToo #TimesUp
