For the older cats not aware slap boxing is considered fine quality sport in high school hallways these days. Two dudes love tapping each other wildly and usually it looks soy as fuck and nobody is actually slapped. I was always disgusted by it when I watched it because I've never seen something so pussy before...me and my friends would play "kill each other" in our front yards,and when we got older we'd add a ball and play smear the queer, but I guess if you never had that this is a decent substitute.
For harmless fun locker boxing is way better.
I figure a lot of kids in my generation didn't have this stuff growing up so i'd say I'm lucky to come from the hood that I did. Always debating and testing when there was no honor and the line had been crossed.
Although i'll admit past generations probably had it tougher than we played.
