We've got a few in our Gaming Group as Khayman (aka Finch) can attest to - we discussed a few of these over a few pints yesterday and he's letting me post 'em. (and a big Hello! to everyone here! I finally made the leap and joined ENworld!)
Anyways, here's a few:
"The Robot..." <DM's face then suddenly goes blank, and hangs head in shame>
- Term used to describe a DM verbal slip-up (i.e. accidently giving away plot, secrets, etc intricate to the current Adventure/Campaign).
Origin: Our good buddy Dylan was running a Traveller game - it was quite intense, and very mysterious at one point. We enter a control room, and sitting behind a consol is an Ancient One - a Droyne! "Holy Cow!" everyone says. "This is amazing!" "What should we ask it?" someone asks, and similar gasps of awe. Dylan had us in the palm of his little DM hand. So, after giving us all a minute to catch our breaths, and all of our attentions are back on him, he starts by saying, "Okay, you enter the room, and the robot..." and then he realized what he had just said, and hung his head in shame. It was quite the event, let me tell you, and no one will let this die (not even Dylan!). So, now we use it everytime a DM screws up somewhere!
"Shopping for Cinnamin Buns" or "Roleplaying Breakfast"
- Term used to describe someone taking a ghastly amount of roleplaying time to do something very trivial.
Origin: I once played a halfling merchant who spent 30 minutes of game time shopping for cinnamin buns. It was quite fun, I must say, and very entertaining. But only for me (and Brett won't let me ever live it down, with such curses in game now as "If you're going to be buying cinnimin buns on my time, I'll kill you!")
And Khayman once spent almost an hour in my Amber campaign roleplaying and chatting with various NPC's over breakfast. Quite fun, again, but only for those immediately involved.
"Can I just enjoy my TURN!?!"
- Term is quite self-explanatory, really.
Origin: WAAAAAY back in the day, a bunch of us were playing GREYHAWK WARS, the boardgame, and if you've played it, you know that after two or three turns the turns become very long; basically, you would take your turn and come back in an hour as the other five players took their turns. Well, my poor brother Richard was the last player in the turns, and of course by that time everyone was slavering to get going to the beginning of the round where we could collect gold/armies/items/etc. Well, needless to say, after a few of us (quite innocently, really) asked if Richard was finished his then current turn, he turned (and pounded his fist into his palm, I believe), and with much conviction bellowed the above phrase. Quite funny. And it has lasted this many, many years.
Keep this thread going! I love reading everyone's In-Game slang! There's some good ones here that Khayman and I may have to adopt (heh-heh).
