Q,

"Gyp" [gipped] had that meaning [getting ahead of someone in line]when I was growing up in Atlantic City, New Jersey in the 1950s. It may even predate that. Another word for gipping is 'bogarding' {I believe this is from Humphrey Bogart}.

I believe that the other definition for gyp-"being cheated out of something" was also used when I was growing up. And both of them are in current use in my adopted hometown of Pittsburgh, PA.

Maybe this [usage]is a Black thing, but I rather doubt it is confined only to us.
