Pasrtymama, my politically incorrect 2 cents worth. I used to work at Sambo's. Still have the wooden nickel coffee chips. It was not racial, it was an OLD story, it was then hijacked and corrupted to be a racial epithet. Gay used to mean carefree and happy, now?!?! You cannot go through life catering to the whims of every single person or group who thinks they've been wronged. I eat crackers, and, to some, i AM a cracker. To others, I'm a "Gringo, pato salado" (zapato?) White guy with salty feet(shoes)? What the heck does that mean, and why would I care? You want ot offend me, don't choose my race, tell me I'M lazy, I'M whatever.. I can't choose my race, but I choose my charactor. Oops, my soapbox is collapsing so I'd better get off it. I'M a lousy carpenter.
Patas saladas goes back to the Mexican War. It was "Gringos, patas saladas." It meant that the Mexican Army was going to drive the Yanqui invaders back into the sea. It sure didn't work out that way.
"Gringo" came from some song the US Army used to sing, "Green grow the rashes oh" or something like that.
The term "Hooker" came from some ladies of a dubious nature that came along with the US troops to provide prostate therapy. General Hooker always took them along.
More useless knowledge to clutter up your mind.
