How do I use "wet your whistle"?

[SiCantikManis]

Hi,

If I want to offer a drink to a friend, instead of saying "Care for a drink?", how do I use the above idiom to do so?

Can I say, "Want to wet your whistle?" Does it sound odd?

Many thanks,
Cantik

You can say that, or you can say, "Would you like to wet your whistle?"

[Sschmidt]

it's grammatically correct, but want to (wanna) or care to have a less formal feel than would like and imho go better with an idiomatic expression like this

1. Want to wet your whistle?

In BrE, it would sound very jocular; as if you were a devotee of P.G. Wodehouse.
