..........................why is a jock strap so called?

 

[PompeyLapras]

Because it's a strap and it's worn by jocks?

Edit: That's a genuine reply btw, not a joke or sarcastic one.

A protector worn by riders, i.e. Jockeys. Jockeystrap - Jockstrap. Relatively simple, I would have thought.

Well....there was once a scotsman who used to be, shall we say, a bit frugal with the truth, who had a friend that invented a protective covering for the soft and dangly parts of the male anatomy whilst playing sport. His friend named the object "Jock's trap" because it is full of bollox....true story...

 

[Beddy]

Invented in the USA for the protection for the cycle delivery riders. Jock was a the slang word meaning a mans you know what. So the name Jock strap became part of the English language...... (Or American as they seem to think they invented the language)

This is feeling a little like those panel games where you have to tell the truth from the fiction.

Personally I don't think it is anything to do with the Scots or people who ride horses.
