'ave a butchers and use your loaf. I ain’t taking the mickey, this is just the best I could come up with on the gary at work.
Edit: OK, to make a game of it, two goals: “most incomprehensible post”, and/or “most evocative post”, depending on which side of the pond you are on. I’m about 16 years and a few thousand miles removed from the environment, so I’ll be struggling to compete. Honestly though, I still sometimes use slang without knowing it is slang, even after all this time.
