Debbie or Debbies refers to a group of girls, who all act alike, look alike, or very similar, and who blabber on about nothing we normals would care about - ie; the real blah blah blah. Debbies tend to think they are better than most ppl, walk around with a very high and mighty attitude, and love to give you looks of disgust, or 'what the hell'. Debbies are known to run in packs, or doubles. Usually Debbies are the drunk sloppy playboy wannabes at the bar.
"Look at that group of Debbies hanging off that guy.. Just so sloppy."

shortened from the recurring Saturday Night Live skit, Debbie Downer, a "debbie" is a person who consistently makes negative and cynical comments. She brings everyone down with every comment. On the skit, her conversations killers were always followed by the classic "waaan waaan."

Debbies, or dbs, is short for douchebags. If you want to refer to a group of lowlife scumbags who have no business existing on this planet, but don't want to be too obvious about your true feelings (or have an aversion to the word douche) use this term. This term can also be singular, as in a debbie.
Friend 1: I think I like men who wear Ed Hardy, GTL and spike their hair.
Friend 2: So, basically you like debbies

Person 1: Well, I thought I liked this guy. But when I found out he was dating my best friend after telling me I was the one, I realized he was a total debbie.

Probably the most narcissistic person you will ever meet! She loves herself the most (more than everyone else). She is going to marry herself... In the end, she can be okay (sometimes... results may vary).
Debbie tried to write her own definition.
