Brown paper bag lunches used to be common but you rarely see them anymore (where I'm from) despite the phrase "brown bagging it today" (or something similar) still being used.
In porn, the "lesbian" category is inside the "straight" section and women are expected to play with each other in threesomes. But if men play with each other it is "bisexual" and locked inside the "gay" section. It is a weird double standard nobody thinks a about.
