Way back when, possibly in the 1950's, it was a simpler time.
A time when if you wore a baseball cap, it meant you were either a baseball player, or a 10-year-old boy.
Now, unfortunately, it can mean so much more.
MAN-LAW #18: Put Down The Hat
I think we can thank Fred Durst, singer from 'Limp Bizkit', for this one. But if you go out anywhere (bars, clubs...etc), it seems like any guy that wears a hat, is a warning symbol of an incoming d-bag.
Now a red Yankee cap is the biggest symbol of someone who can potentially act like an asshole. To be fair, anyone who wears those gang looking/multi-colored caps looks like an ass.
I really have no where to go with this, other than saying, "Guys, how about we grow up a little!"
