My fraternity would have been punished for those signs back in the 1980s. We had a pretty comprehensive list of behavior rules as a recognized organization. One was put on probation for rating women’s looks as they walked past their house.
Back then, to get a fraternity in trouble publicly you had to collect evidence, call a newspaper and convince someone to do a story on it, then the story had to get picked up nationally. Six guys were suspended by RPI for a game of “rodeo” in 1989 when USA Today got ahold of the story.
DISCLAIMER: Never do this. Rodeo - a guy grabs a woman (usually in a college bar) around the thighs from behind and bites her butt. Another guy times it - 8 seconds is a “full ride.” The “rodeo clown” apologizes for the drunk friend while the rider sneaks away.
