(trigger warning) Please pardon the indelicate subject, but is it possible that the word “Persian” was not flagged as an ethnicity per se, but as a check for prostitution?

The description, “momentarily persian experience”, sounded a bit edgy when I first read through, and there are certainly escorts online selling “the Persian experience”. Although, there is not an obvious, say, Urban Dictionary- scale entry for the phrase, the way “Greek” and “French” are.

It might be exactly as you described, but I thought I’d offer a non-obvious alternative for consideration.
