I didn't mention it cuz I figured if they're monitoring calls for it then they're damn sure monitoring posts for it and I didn't want to end up on a list. But what the hell, I'd rather learn more about what this is really all about. And that's the thing: the word wasn't even that crazy, unless you're on line at an airport (apparently) which I wasn't.
The word was "bomb".
(...Now that I think about it, I was at a train station. Not a major one though, doubt if that's related.)
