I encountered for the first time the word 'swanging' (swangin') in a song done by the Bay City Rollers (I know, I know). I did a little browsing and can't get a meaning for it. The line was "somebody said that they saw me, swangin' the world by the tail". It seems to have a usage in rap music, also. Can anyone out there in Mudcat Land enlighten me? I know that the occasional 'good ol' boy' will use that as the pronunciation for 'swinging', as in "I was swinging on the tree limb." However, I don't get it. I expect the word is new to the language. Has it made its way out of the USA?

Thanks, y'all.
