I am studying chinese and often in movies i hear something like "jin kuei". Could somebody tell me the correct spelling of the word?

見(means see, pronounced “jian”, forth tone )鬼(means ghost, pronounced “kuei”, third tone)
This is a spoken phrase used when someone sees something that is totally illogical, absurd or ludicrous.
For example, if you stayed at home all day last Sunday, and you got a speeding ticket from the Police Department saying you drove on the freeway last Sunday (Ex: Someone used a fake placard with your car plate number), you might say “Jin Kuei”.
