This is something i recomend especially when your playing contacts sport.A spandex are basically tights you wear underneath your shorts when playing ruthless sports like rugby and aussie rules because if you wear boxers your balls might hang off the side and that could creep people out.
Mate1:"Dude i think you should get some spandex im kinda getting sick of looking at that thing."
Mate2: "Oh Ya Reckon!? Yeh man i think your right. i was getting tired of people looking down my balls all the time."
