The neglected appendage or when left means right
Metaphorically speaking, a left-handed man has a longer hike down the same path than a right-handed man does when it comes to adjusting his underwear.
History has not been kind to the left-handed man and his briefs until one British manufacturer defied the laws of right-handed logic, and the vertically inclined, by changing the opening in the front to a left-handed horizontal “hallelujah.” A bold yet daring move that will possibly overshadow the creation of men’s underwear itself.
“. . . Y-fronted underpants have traditionally had a right-handed opening from the time they were invented in 1935.
“As a result,” Debenhams said, “left-handed men have to reach much further into their pants, performing a Z shaped maneuver through two 180 degree angles before achieving the result that right handed men perform with ease.”
A Z shaped maneuver that Zorro would have likely performed at ye olde urinal while holding his sword.
