It's something you call a person with a flock of seagulls hairstyle, which was the trademark of the 80's new wave band "A Flock of Seagulls"
Jules (Pulp Fiction): You, Flock of Seagulls, you know what we're here for??
Roger a.k.a. Flock of Seagulls: Yes
Jules: Then why don't you tell my boy here Vince, where you got the shit hid.
A cop or a police officer in the United States!!
The Wolf: Now, if we come across the path of any John Q Laws, no body does a fuckin' thing till I do something. What did I say??
Jules: Don't do shit unless
The Wolf: Unless what??
Jules: Unless you do it first
The Wolf: Spoken like a true prodigy
A German phrase meaning until we meet again or till I see you again, used as a farewell.
This is the formal and polite way to say the goodbye.
Dr. King Schultz: Normally Monsieur Candie, I would say, auf wiedersehen. But since what auf wiedersehen actually means is, till I see you again, and since I never wish to see you again, to you sir, I say, Goodbye!!
