Contrary to popular belief, the lexeme of Jobbie doesn't have anything to do with defecating. A jobbie can be a thing or place.
1) I am trying to jimmy
this jobbie open, but this jobbie won't jimmy
. (OR, in ordinary English: I'm trying to pry this thing open, but this thing won't be pried.)
2) I'm all alone in this jobbie,
No one knows if I'm nice or snobby... (rhyming couplet)
