The term "Pogues is derived from an Irish band called The Pogues, which was originally named "Pogues Ma Hone", which is Irish idiom/slang for "Kiss my arse". The band was forced to shorten the name in order to enter some musical markets, and the meaning of "Pogue" drifted from "Kiss" to "Kiss-arse" to "someone in a very disadvantaged position", which is how it's used here.
