Ordinarily, the direct-quotation translations like this in my walkthrough are only going to be for big background-related or major story-related things, where knowing the exact words is really helpful. This is kind of an exception to that rule, due to the silliness of the joke's premise:
KF(S)-Lena calls the other girls together. She figures that since the boys are lousy at magic, and really arrogant, she can probably trick them into giving up the better half of the floor (the right side, away from the stairs). She asks the girls if they know the phrase "Ladies First", and then continues to trick the boys into giving up the good half of the floor. (Note: this joke -really- does not translate well, but I'll try anyway...)
Lena: Oh there's just something that, you know, every guy knows about. I'm sure that you'd know about it too, Ant.
Rick: There's nothing bro don't know!
Kule: Of course!
Lena: Well... you must know what Ladies First means...
Kule: Ladies Fast... yeah
Rick: Ladies Toast?? What's that?
Ant: Of course I know what Ladies Fist is!
Lena: Well, do you care to show us?
Ant: Sure, um...
Lena: I can just get Ellie to explain
Ellie: Well, Ladies First means that boys should show respect to girls by letting girls go ahead of them.... Otherwise, you look selfish. Ant, you don't really want to look like you're rude and don't respect girls, right? I mean, you did say you knew what Ladies First meant, right?
Ant: Of... of course! See, I know what it means. You can go on ahead. Ladies Fist!
Lena: Ok then. We'll take the right side of the room.
Ellie: Thanks, Ant!
Rick: Cool, bro! You totally showed them what Ladies Toast is.
Ant: You idiot! It's Ladies Fist!
Rick: Ladies To...ast?
Ant: No! Ladies Fi...rst...?? Man, I don't know.
