it is pronounced with a hard 'an' as in "can't". But it is in the first place a slang word meaning "sexually arousing" and many French would have a bad idea about someone saying that.
The French "r" is really hard to describe, but if you substitute the American "r" you're generally still understood. So it would sound like "frair."
