it's been fairly well stamped out i think. Don't hear it in media or the mask off cracker to cracker communication around here anyway, maybe it's more of a lingering thing in the plains states.
I grew up with the hiking spot for my family being slur peak and now live a day trip away from slur valley (which just got renamed) and I've never met someone who wasn't native that even knew it was a slur before things started getting renamed. You've got to be like a 1800 elo racist to use it.
Weird thing is it's only called that way if you switch it to english. Was looking at the italian menu and couldn't figure it out since there were also weird names on but the one you mentioned is just called rib eye so I immediately scrolled over it.
So most probably at least nearly nobody is going to order it with that name, can't imagine them having a lot of english menues available outside the airport locations and the ones in the centres of big, touristy cities.
