If someone asks for something or you offer something that you don't have or don't want to give them you say skwahn to signify that you aren't really going to give them it.
Nick: Hey, can I get a piece of gum?
Mike: Sure... SKWAHN!

Thomas: Hey, you want this computer?
David: Sure!
Thomas: SKWAHN!

James: You think I have a chance with that girl?
Mike: Yeah definitely... SkWAHN!
