This is the first time any of the players has actually paid attention to the random "alien language" that the GM has been using occasionally to provide atmosphere and set a scene of an alien world. Our GM is evidently not a conlanger.

The language as used in the films is called Huttese, and is a lingua franca of much of the region of space in which the movies take place. It was first spoken by Greedo in A New Hope, and based loosely on Quechua, but evolved over the other movies. There is a moderate-sized known vocabulary of translations of Huttese words and phrases into English, but it isn't as complete a language as, say, Tolkien's Quenya, or Klingon. (The previous sentence is not meant to imply that Tolkien invented Klingon. If only I'd written it in Lojban, I wouldn't have to qualify it now. Although it's an amusing idea.) The grammar and sentence construction of Huttese as used in the movies is basically ad hoc, with no known rules.

{Sebulba sneaks over and does something to Anakin's pod}
GM: Hmmm.
GM: <roll>
[SFX]: SNAP {snapping off a part of the pod}
[SFX]: ZZZT!
{Sebulba goes over to Anakin, who hasn't noticed}
Sebulba: Bazda wahota, shag. Dobiella Nok.
Sebulba: Yoka to Bantha poodoo.
Anakin: Cha skrundee da pat, sleemo.
GM: Um... what did you just say?
Anakin: Well you said, "You won't walk away from this one, slave scum! You're bantha dung."
Anakin: So I said, "Don't count on it, slime-ball."
GM: Uh... Wow. I was just using random syllables.
GM: You were supposed to ask me what Sebulba was saying.
Anakin: It's more important to stay in character though, right?
Anakin: Okay, I rolled a 9. Is that how it works?
