mubble fubbles, n. [‘ A state of depression or melancholy; despondency, low spirits. Chiefly in in (also out of) one’s mubble-fubbles.’]

From the OED WOTD



If one was inclined, in fact, to take up residence in a dumpster, would this sign be likely to discourage one?

Also: I suggest replacing “or” with “nor.” Better yet, change word order: Do not occupy nor play in, on, or around this equipment.”

Actually, the Spanish-language version seems better put. “Don’t occupy it either.”
