TUFF GUY...NOT HAVING A GOOD TIME?

I keep running into these "Tuff Guys" at parties, bars, and clubs and I am confused about their motives for being there.  We've all seen them.  They walk around the venue like their sole purpose there is to find someone and just kick their ass.  These are the guys who go to parties to "be cool" or "just chill and drink" and "look tuff".  These are the guys who, when I'm having a great time and go to give them a high-five they just look at me like i'm retarded because they are trying to "look tough" in front of everyone else.  And these are also the guys who never get the girl because, well, their personalities just plain suck.  People go to parties, bars, and clubs to have a great time.  On average, I have a smile on my face 60% of the time when I'm out.  Not that I've consciously took note of it but I'm a pretty all-around happy person at this point in my life and people gravitate to that.  I love talking to people.  And if you talk to a lot of people, a lot of people will, in turn, talk to you.  My philosophy is: Approach easily, and get easily approached.  The more you approach and talk to people, the more social proof you have.  People see that other people accept you and like you so they find it easier to approach you. That's right, a lot of times people will approach you if you have enough social proof.  That is the essence of social proof.  There is a term for this theory in consumer psychology.  When a lot of people are purchasing a product or taking part in an event, other people will often naturally gravitate towards it just because a lot of other people have approved of it by purchasing or partaking in it.  You are the product.  Other people are partaking in the fun and positivity that you have to offer.  Haha, never underestimate the potency of a trend.  Be the trend that everyone is talking about!  When you are a friend to all, and bring positivity and good emotions to the venue, you create this buzz around you that people want to be a part of.  The life of the party, so to speak.  Life can be amazing.
Signing off.  Cheers.
