Balls, Nuts, or Testicles!
I think they're more than equalizers. I think they are unbalancers. One hard kick from my sis and I'm on the ground for quarter of an hour, with no strength left at all. One hard kick to my sisters crotch and... it hurts for a second...
You might be right. About 15 to 20 minutes ago, my girlfriend lightly slapped me in the nuts. I actually groaned out load. I didn't drop suddenly on the floor because its not as hard as a kick, but I did go down for about a few seconds. It still hurts in my balls and my stomach. I slapped her in the crotch to see what would happen and she flinched a little, but then she laughed.
Same dude. My sisters were all over my balls! My mom evern nailed or squeezed me a time or two!
Good for your mom. Mothers should bust theirs sons balls more often.
