Years ago, as a camp counselor for the young teens of my church, we had a night of split activities for the boys and girls. As the girls went off to have their nails done, the gentleman stayed in the cafeteria/gym to have various types of physical challenges (most notably the push up contest, which one of my campers easily dominated).
Toward the end of this, the girls came in, complaining right away about a smell that none of the males could register. One of the camp’s leaders quickly quipped,
“Ladies, that is testosterone.”
