A casual reference to someone that you don't hate, but think is a really huge loser. There is no reason for thinking he is a loser, he just is.
Generally, dink touchers are super nice guys with lots of friends. However, when you meet them, you just think: "man, this guy is a huge dink toucher."
When you are hanging around with dink touchers, you generally pretend to be friends with them. But when you get home, you complain to your wife/girlfriend about how much they suck and that
you don't want to hang around with them any more. Then your wife/girlfriend gets mad at you and asks you to explain why that guy was a dink toucher. You don't have an
explanation and lose the argument. Then you end up hanging around with the guy
over and over again.
