How did you find out that a blow between the legs hurts men?

I have a brother.

Soccer!

Football to the balls... You learn quickly to protect 'em.

I saw it on an episode of The Simpsons.

Witnessed some kid the other day take a knee to his nuts in the pool and it was hilarious

For me it was a tv show, can’t point out one specifically. It seemed to be a hallmark of early 2000s humor

It was a fact taught to me at some point I dont remember. Then i was hit by a thrown bar of soap in the nuggets and realized how severe the pain was.

I never understood this and still cringe when I see guys drop to the ground when hit in the sack. My explanation: bitches. This or I have ballz of steel. Been kicked two times and punched two other times in the scrotum and never flinched an inch back. One time it was a particularly gruesome and epic scene, worthy of a school bullying movie.

You need to allow multiple selections:

For some weird reason my school thought it was hilarious to full force kick eachother in the balls. There were no survivors.

It was either when I hit my self with a yo-yo or when my 2nd brother punched me in the ballsack.

saw it on America's Funniest (Home) Videos often

I was taught that as a self defense method from an early age.

Yep if men get rack in their Nut sack they will fall in pain believe me I been there.i got rack playing football so yea ouch!!!!
