To Twi'lek language: ****, Whore, Bitch, traitor, Foolish, Idiot.
Its meaning will vary comes to context.
For Example:
Queen Talia: That Schutta
In that Context, She is saying that Valku is an idiot.
Another Example:
Atton: Why dont you Schutta go away.
In that Context, he means ****.
From what I do understand that NO ONE likes to be called a **** or an Idiot.
