You know what, I've only ever heard the word "hinky" once before. It was in the film The Fugitive when Tommy Lee Jones' character Samuel Gerard is talking to his colleagues whilst waiting for an elevator.

Marshal Biggs: "This is hinky. This guy's a college graduate, he went to medical school, he's not gonna come through all the security, go to the county lockup, to find someone his people say doesn't exist. Hinky."
DM Samuel Gerard: "Well, what does that mean Biggs, 'hinky'?"
Marshal Biggs: "I don't know. Strange."
Marshal Henry: "Weird."
DM Samuel Gerard: "Well, why don't you say strange or weird? I mean hinky, that has no meaning."
Marshal Biggs: "Well, we say hinky."
DM Samuel Gerard: "I don't want you guys using words around me that have no meaning. I'm taking the stairs and walking."
Marshal Biggs: (Whispering) "How about 'bullsh!t'? How about 'bullsh!t', Sam?"

I'm with Gerard, hinky is a terrible word.

I'd like to take this opportunity to say that trying to get a platinum trophy in a Naughty Dog game is smurfing impossible. Good luck if you are attempting it, Formy!
