How come the majority of people on myspace have pictures of themselves getting drunk?

Basically, because they think it makes them cool. Not realizing that they actually look pretty foolish.

Well i wouldn't say it's the majority but I'd say people do it to show that they are popular enough to get invited to parties. And younger people do it because they think it makes them seem older and more mature.

Because they don't realize that future employers will look at those photos and pass them over for employment.
