I'm 20, couple years out of highschool, but this **** definitely was going on at my highschool when I was there.
Funny thing it was only the "in crowd" of guys doing it, lol. I was constantly asking myself "How are THOSE the people everyone likes?" at my school. Dunno what they called it, but one ****** tried to get me once and I gave him a nice jab to the cheek.
I was immune to nut slaps from then on, but I have to say, it was pretty funny watching somebody else get it, lol.
