if you don't particularly like someone and they chat to you all the time about their life you could simply reply with fairs to whatever they say. They would soon get the hint that your not exactly interested in whatever it is they have to say.
Fairs is an extension of fair, or abreviation of fair play. It is certainly not a cuntish word. Anyone that believes as such, is in fact themselves a cunt. If they are called Steve then they are a cunt by birthright and the point is mute anyway.
Many countries gather at what they can the Expo, Exposition; & there's lots & lots of very cool stuff to see & do. Really awesome to hear so many different languages spoken! Interesting to see all the different cultures!
