Bryan, Bryan, Bryan... poor choice of words, "I'll bite".... but since you've asked... the rumor that I've heard is as follows;

Allegedly, when Hard Rock presented it's original artwork to Gaming approval for their Cinco de Mayo chips, there was a pink taco illustration above the Mexican's hat. Gaming turned down the artwork because they felt is was obscene in that "pink taco" was a reference to female genetalia. So when the pink taco club convention chip was issued, which did not need gaming approval ... because it was a non value chip ... some gaming board members felt that an end run had been pulled off by Hard Rock after being denied permission to use Pink Taco on the Cinco de Mayo chip.

Believe it ... or "bite it" ... that's the alleged rumor I've heard that no one wants to speak about ... and as Paul Harvey ends all of his radio commentary ... "Now you know the rest of the story."

Perhaps some Las Vegan will want to deny or confirm the rumor.
