Commando

In my day - which, if you haven't noticed, includes today - "commando" stood for tough military types you sent in on impossible missions.

Apparently, today it also means going about without your underwear on. Now, I do this all the time WHEN I'M SWIMMING.  And, to my dismay, curmudgeons have been known to do this occasionally because they do forget things now and again.  

But on purpose?  How, err, painful.  I like to protect the boys.
