Something which has been wombled has been 'taken' from where it was was randomly
lying around. This derives from 'making good use of the things that we find, things that the everyday folks leave behind'
To
go 'wombling' is to go in search of said items, on a mystery tour of sorts just to see what
random things you can find.
We went on a mental road
trip and wombled this walking stick which we found at the side of the
road.
or, Someone totally wombled my last chip off my
plate.
