In my understanding, the word 'cheeky' refers to a child talking back or being rude.
Over the last few years, I've noticed people using it when referring to going out for a drink - as in 'are you up for a few cheeky drinks?' Why? If I was a 15 year old sneaking out to drink cider at a bus stop then i could possibly understand why the drinking might be considered 'cheeky'. But not when I'm a grown woman going out for a drink on a Saturday night.
There's an advert for mineral water at the moment where the guy talks about having a 'cheeky Volvic'. It makes me so angry! My brother is a bit of a 'lad' and is always going on about 'cheeky drinks' (and 'banter' too, but that's another AIBU) and it drives me mad. So am I being unreasonable in wanting to scream at anyone who talks about having 'a few cheeky vinos', or is this a perfectly acceptable use of English?
