Yea, once your out of high school, you will start to love life.
I think a large part of the problem is that when people from high school get to know you, you are a lot younger and a lot more immature then you might be in your later high school life. You haven't yet picked up on the same social skills that others have, and because of this you are made out to be a target, and this follows you no matter what you do. It is a pit that is very hard to dig your way out from.
But once you leave high school, you also leave that reputation behind, and you get to start again as a more mature person who, although might not be the most social person in the world, they are 'normal' enough to not be constantly attacked. Further more, I have seen people who had strong and large social circles in high school do poorly with friends later on because they became so adapt to that specific circle, they couldn't go without them, and they weren't adaptable enough to make a lot of new friends. Although far from a sure thing, this seems to happen to douche bags who are making attacks on the 'nerds' far into later high school.
By the time you go to collage, or uni, or what ever they call it where you are, or get a job, people don't find that shit nearly as funny, but these people have been enjoying that as the social norm for years, and when not in this close group who also see being a douche bag as normal and entertaining, they don't fit in as well.
tl;dr: High school sucks.
