made some sound with fingers close to my face
My boys at work flick their hands so that their fingers make clicking noises (sorry.. if you know the action I mean, its not that easy to describe in writing!? Haha)
Anyway, they told me if they do that to someone it means a big fcuk off - thats their words.
Ironically though in the UK some people do that when something is cool or really good... so I expect this could lead to a big misunderstanding if an English guy does this gesture to one of the Polish guys!
