Does pretentiously reverse-snobbish count?
If so, the time my mate insisted 'I know what it's like being working class. My parents are doctors and doctors work'. At the time they were busy paying for him to do a second degree because diddums didn't enjoy the first one ...
My aunt told my mum she was considering 'pensioning off' her Dartford wineglasses and buying some Waterford Crystal '... because [son] is 21 now and will be wanting to have dinner parties'.
This isn't awful, but was cringey at the time: a bloke I went to university was called by his middle name, not his first name. Every time someone teaching us went to check, '... so, it's Bob, not Jim' (funnily enough those aren't the real names), he'd jump in and say 'yes! Jim, like Jim FamousMan, he's my great-uncle and I'd hate for us to get confused!'
I still have no idea who Jim FamousMan was, nor did any of my teachers ever let on they'd heard of him.
The same bloke, when we were all getting to know each other, came out with the wonderful line: 'Oh, so some people didn't do four A levels then? How funny! I suppose if you are counting general studies, I have 6, actually ...'
I'll refrain from pointing out what he's not doing with his life now ...
