A person who is intentionally starting trouble, but pretends not to be, is creating Barney Rubble Trouble.
At the football game, Tim belittled the opposing fans by shouting names at them. When the stadium security guard came around, he told Tim to have a good time in the stands, but to not start any trouble. Tim replied, "No trouble, no trouble, Barney Rubble." Tim was creating Barney Rubble trouble because he gave the security guard the impression that he didn't mean to start any trouble when he really did.

Get the Barney Rubble Trouble mug.
Stale weed, an almost dusted bowl, or an almost empty bag of weed that just has a few crumbs left
Stale weed or an almost dusted bowl.

This weed must be pretty old it tastes super Barney.
You might get another hit off this bowl, it’s all Barney rubble.

All that’s left of that ounce we bought is a half a bowl of Barney rubble.
