I just got up from conversation with a couple of older black men, that I said “well I got to go back to work and start cracking the whip.” And it occurred to me then that it was probably a really insensitive stupid thing to say.
Sadly, it hadn’t occurred to me until it’s already said.
There’s an older form that goes back to at least the 1970s when fuel efficient Japanese cars started to become popular in the US: “Rice burners.”
There was some made-in-America angst at the time because of the oil crisis, coupled with some quality issues that made these cars more appealing. The phrase was definitely used pejoratively. I can remember my dad muttering about it well into the '80s.
