this guy that answered first said it is some guys "niche".......do you know what the word niche means? someone's niche is pretty much their "role" or "job" in their environment. how does that relate here?



its called celebrating. their is no "meaning" of these actions, it is just pumping up the crowd or letting out adrenaline in celebration. have you ever seen tiger woods pump his arm after he hits a big putt? have you seen brett favre throw his arm through the air after throwing a touchdown pass? have you seen soccer players run around in circles with their arms out?



all celebration rituals. not signs with meaning. they arent speaking a language or anything.



now sometimes you will see someone like steve mcnair put his hands out and i think it is the same thing you are talking about emulating a bird. this is a sign of the fraternity he was part of in college. i believe it is the q dogs (nickname of the frat).....so yes some of these things are signs, but chest beating and everything else is just celebratingWhat is the meaning of the signs that Basketball player do after a dunk or any sensational action?
