This is a good subject for making your conworlds seem more alive. Consider the following remark, which one might use to assert one's presumed sociocultural superiority over another:
A contemporary example has X = "listen to", Y = a popular musical artist, Z = a less popular but more 'credible' musical artist.someone said, or perhaps wrote: Why do you X Y? That is so lame! Anyone with any credibility X's Z! Everybody knows that!
What would have been an equivalent in (for example) Roman imperial times, the Middle Ages, Elizabethan London, or Georgian London when consumerism had started to become common among the middle classes? I imagine one Roman one might have X = "follow, support" and Y and Z = two of the chariot-racing teams, where the relative successes of Y and Z have particular and possibly very sensitive connotations.
Or, in shorter form: what would be typical popular-cultural reference points?
