Kids and slang, it's a tricky decoding challenge. Could be a drug reference as newbie says. Could be a video game
reference, as several others have pointed out. It certainly bears investigating, but I wouldn't jump to the worst
conclusions until you've looked a little further. Sometimes/often drug culture slang will be adopted innocently for
more innocuous activities. But you're a good parent for picking up on this and being concerned. You don't want to
jump the kid about drugs unless you have cause. The kid will really be alarmed if you draw that conclusion and it's
something ordinary. Sometimes just talking to the kid helps. You could ask him off handedly about the slang, not
mentioning where you heard it, and see if he looks uncomfortable or defensive. Just say you heard a kid saying it and
wondered what it meant in the current lingo. Then read your kids non-verbal signals. If he comes up with a video
game explanation, ask to see the game, in the spirit of inquisitive fun.
