This question is a little difficult to interpret, so here’s two options of advice.
1. Make pop art of things in everyday life that became pop art culture, for example: Marilyn Monroe, cartoon women, canned soup, ect.
2. Make a pop art painting of anything now a days that everyone knows of, for instance: Chick-fil-A, Nike, football, Taylor swift, ect. All of those reflect now a day culture.
Best of luck to you artist!
