It will be harder for some of the younger guys on this thread to recognize this, but as you get older you realize the impact your actions can have on others' self esteem.
Being an a$$hole may seem funny at the time, but you can really hurt the self image of someone who was kind enough to pose for our fine site.
Once I was driving down the road and a young girl at a bus stop (not particularly attractive) jumped off the curb in front of my car (but out of harms way), lifted her shirt and flashed me her breasts.
It was unexpected to say the least, but I could have though ewww, but instead I realized that I just got to enjoy free breasts for no apparent reason. Although not the best I've seen, it was hands down the best part of my drive to work that morning. Appreciate these women for what they are. They are certainly not unattractive, and if you are doing better than that, good for you! But don't be a$$hole.
