Sagging is apparently now such an important part of an 18-year-old male's identity that all of the male lifeguards at the lake in which I swim put underwear on under their lifeguard swimsuit, So that they can sag their swimsuits and show their underwear. Look, I used to wear one of those lifeguard suits all the time: They have their own built-in underwear. Putting another pair of underwear under them is totally superfluous and awkward. But apparently being seen in public without your underwear showing is just not on. I wonder though: Have they given any thought to the fact that this will certainly slow them down should they ever have to go save someone?
