The phrase "brown paper bag test," also known as a paper bag party, along with the "ruler test" refers to a ritual once practiced by certain African-American sororities and fraternities who would not let anyone into the group whose skin tone was darker than a paper bag. Spike Lee's film "School Daze" satirized this practice at historically black colleges and universities. Along with the "paper bag test," guidelines for acceptance among the lighter ranks included the "comb test" and "pencil test," which tested the coarseness of one's hair, and the "flashlight test," which tested a person's profile to make sure their features measured up or were close enough to those of the Caucasian race.
