Is it normal to steal sweaty jock straps from a laundry bin?

When I was in high school, one of my classmates recorded stats or was some type of waterboy for the football team. A few weeks into the season, the coach discovered that someone was stealing used jock straps while the team was in the showers. So the coach set up a sting where one of the players hid behind a row of lockers to spy on the laundry bin and caught this kid reaching into the laundry bin to take a few sweaty jock straps, which he then shoved into his book bag.

This kid was effeminate and I am pretty sure that he was gay. The rumor was that he would bring the used jock straps home and sniff them while pleasuring himself.
