I think we can all agree that this is one trend which needs to die. No one is interested in what boxers you are wearing. If this is being done for the better ventilation and airflow, then try wearing shorts.
After being forced to use a Mini-Van through my pimply faced, innocent high school dating years, I came up with a list of benefits which Mini-Vans offer to those who prefer to hunt hookers and hitchhikers.
I went to church one time back in high school (I heard something about a free pancake breakfast afterward and I was locked out of the house after a series of unfortunate events involving a fire extinguisher, two hookers, and a trumpet), and I learned a few things about chicks that have values and a faith life. Dating a religious girl is a lot different than dating a normal human being. They do creepy things like refuse to abort their kids, buy giant rosary beads and use them for their anal cavity, and talk about God a lot.
