My "metalized paint" post conjured up an old, unrelated memory.
When I was in school, I worked in the Combat Zone in Boston. Kind of a seedy sort of place (and I'm being kind :> )
One of the guys I used to encounter regularly had a guest with him one day. Conversation turned to "employment"/careers.
In a very casual manner, this guy's vocation was described as "He and hangs wallpaper" -- or something like this. It made no sense to me and they both enjoyed a laugh at my expense.
When "translated" into plain english, it was something along the lines of " and writing bad checks" -- *professionally*.
So, my question: what was the likely phrase that was initially used (mumblemumble) and what was the correct "translation"?
