Y-fronts
From Wikipedia, the free encyclopedia
Y-fronts is a British colloquialism for the type of men's briefs that have a sideways-slanting fly.
The term derives from the inverted Y-shape formed by the seams of the underpants.
They are a fashion item that is making big comeback as more and more men feel they are more comfortable than boxer shorts and considered by some healthier than tight fitting briefs.
