Kea (from out of nowhere): "Wanker"
Sierra (incredulous): ".... what?!"
Kea: "Wanker. I don't know why, I just felt like saying it."
Sierra: "Do you know what that means?"
Kea: "No, what does it mean?"
Sierra: "It's a person who beats off a lot."
Kea: "... oh... Is that what 'jolly wanker' means?"
Sierra: "I didn't know that was a term; is it British?"
Kea: "Yes."
Sierra: "Then yes - that's what that means."
