You want to call someone a real slimeball in Huttese, you call 'em "sleemo." You want to say they're worth nothing to you, call 'em "poodoo." You want to get somebody's attention, you call out "chuba!" That's like "hey, you!"

A barve is, technically speaking, an animal raised for meat. You call somebody a barve, you're saying they have an... unclean reputation.
