“Dodgy” is a very commonly used word in Britain, especially in informal conversation.

The general meaning is “suspicious” or “unreliable”.  The most common situations in which “dodgy” is used are:

a)      People

e.g. I wouldn’t lend him any money, if I were you.  He’s a bit of a dodgy character.

 b)      Machines

        e.g. I bought this old car very cheaply last year but the engine’s a bit dodgy.  It makes funny noises when I drive over 60 miles an hour.  I don’t know what the matter with it is.

        c)  Situations 

        e.g. I got a call yesterday from a man offering me a million pounds if I gave him my bank account details. The whole thing sounded very dodgy to me.

There are some example sentences here.  http://fraze.it/n_search.jsp?q=dodgy&l=0

I’m looking forward to some good quality sentences which use the word “dodgy”.  But this time, I don’t want to see any dodgy efforts!
