Someone who thinks he's always right; an asshole. Dan is someone who will have fun at someone else's expense.

Get a Dan mug for your fish Beatrix.
1.) An immature, insecure, childish, self pitying man who has no job, no friends, no motivation, no class, lives with his mother past 21 years of age and mooches off anyone around him.

2.) Someone who's penis is either so small or so thin, you can't even feel it. It can't even be measured on the 0-10 scale.
"Are Rebecca and Chris still dating?"
"Yeah but he's a total Dan. She can do so much better."

"How good was the sex?"
"UGH, it was a Dan."

Most appauling person you will ever meet. He'll love you one day, and be content with being "just friends" the next. He'll also expect you to be totally fine with it as well. He's a smart, arrogant ass who is impossible to get off of your mind. Dont get involved in him! He'll only hurt you worse than you could ever imagine, yet you'll still be drooling over his every word when all is said and done.
Brother: Who's Dan? Your boyfriend??

Girl: *bursts into hysterical crying*
