We are talking about fisticuffing, something that most young Americans no longer know how to do.
In a bar room brawl or at some party you're not fighting like your in the ring.
There are also rules, you never kick someone who's on the ground.
I remember back during the 90's when Marine DI's were noticing that recruits were showing up at MCRD and not knowing how to fisticuff or have never been in a fist fight.
Even Sonny Barger in a L.A. Times interview mentioned that today's younger generation don't know how to fisticuff. Instead they use bats, knives, and guns.
