1. Jockstrap (athletic supporter). A type of underwear worn during sports or workouts.

2. Underwear that is sometimes required for gym class which gives a perfect target to many middle school and high school lockerroom towel snaps.
Dude, I totally got him good when he was wearin his jockstrap.

The team was required to wear jockstraps for every game and practice.

There will be a Jockstrap inspection before gym class today.
