Lobo: Pliet, sa frag

Fake Tseng: Please, I don't understand. I don't know what you want.

Lobo: If that's how you want to play it? Fine. Contract calls on the Main Man to put on a show for the locals. So one more time: surrender, or die.

Ergo, sa = or, frag = die.

Then later, Lobo says: "Flash sa frag", which made the "Krollo" stop struggling. "Flash" must mean behave.
