Shortened term of Thalidomide, a German-invented drug which was used in the 1950's and 1960's across Europe to tame the side effects of pregnancy. It caused birth defects in new borns who's mother had used the drug.

The ban has now been lifted on Thalidomide as it is believed to cure a rare form of leprosy and is currently being tested for the treatment of HIV/AIDS.

A widely used insult in England, i dont know about America its probably there too. It is quite an extreme insult, most people dont like it (obviously), means spasticated or retarded.
It comes from the German drug that was used in the 60's to help calm the side effects of pregnancy, but sometimes caused physical abnormalities in the baby. A flid is actually originally a person with no arms and legs.
You run like a flid!
Ahhh flid! oh wait you have arms and legs..

abbreviation for Fuckin' Long Island Douchebag.
Things that all Flids know:
1) Northeastern America is a suburb of New York City.
2) The rest of America consists of a couple of farms and the OC (which they know from their favorite show)
3) Dave Matthews totally sold out 3 years ago, John Mayer is like way better.
4) The fact that the Long Island Sound sucks does not stop these people from trudging across the snow in sandals in the winter.
5) Although they love New York, they have never been to the Bronx, Queens, Brooklyn, or Staten Island except to see a baseball game. Also, they have never traveled to any state that does not rhyme with Jew Nersey or Konnektikut.
6) Hat backwards... always.
7) They came out of their mom's womb wearing a pink polo shirt, collars popped, and wearing a diaper made by Ambercrombie and Finch.
