The crunch is the best bit!
Mind you I have no problems eating crisps in public, and I don't have a handbag I have a rucksack. And my coat pockets are big enough to fit a packet in (was very pleased when I discovered this!)
Omg, that must mean I'm a man? 
I always call Prawn Cocktail flavour "girl crisps" to Ds1 as when he was little he took against the colour pink and refused to eat his previous favourite.
I hate them, which goes to prove my manliness!
