Interesting. Never heard this, at least explains part of that quote.
But I get downvoted for asking, while the US people (as is usual) expect people to know some regional slang. Reminds me of this:
TO: "someone was gassed"
P1: "Gassed, what kind of gas?" -250
P2: "They were physically tapped, like a car without gas" +170
Since P1 still did not understand it, people got pissed, even mocking for asking, while the explanation of P2 actually contradicts the real meaning but gets massive upvotes (relative to usual numbers in that sub). You do not need to take my word for it, this is where it starts (who I call TO): link here
