Yes, that's what it's really called. Inspiration apparently came to Andrew Archer during an embarrassing episode with an ex-girlfriend. The concept is simple: it's a pair of boxer-briefs with a special pocket on the inside. Aside from self-conscious men, the inventor has also had positive feedback from sportsmen (who find it comfortable) and, yes, women (who apparently see it as the male equivalent of a lightly-padded bra).

From ABC The New Inventors, which cautions that the Stiffies website contains "blush-inspiring graphics". I found it hilarious myself, but you have been warned.
