"I thought you'd be kicking back today", in light of the midnight crash between the motorcycle, the go-kart, and two ostriches.
(kicking back comes from the Latin ~ Balagopalottoknicker meaning lean back, put your feet on the old balago ottoman, and stick your hand in your shorts)
When you "kick back", "kick it back", or "kick it" what you are doing is relaxing.
One night,
German, Fredrick the Glob threw his legs up on his out of
work Cossack butler who was gathering cold klinkers off the floor, while wearing a bear skin coat. Fredrick sighed and said, "GUTTEN KOSAK".
A passing Englishman, by the name of John Wasserman (which means man who pass much
water from only one
beer) thought he had said hassack. Wasserman rushed
home to
England and threw a sheepskin over a strumpet. Whenever Wasserman was kicking back and havin a cold Leinenkugel's from Bavaria, he would bellow, "HASSACK", and the stumpet came running with the sheepskin blanket.
Englishman, David Stool improved on the hassack. Stool was a furniture maker, and began manufacturing a padded
piece to match his chairs. Thus was born the Foot Stool.
I know this to be
English. One night in a London bar filled with the village people, I heard one man say to another, in a very cockney accent, "May I push your stool in."
Just a tidbit. In 1650, during the Reformation,
English law decreed it illegal to keep strumpets at
home any longer. Sales of Foot Stools increased greatly, and David Stool became a Hundredaire.
Anyhow, back to the meaning of kicking back, if you are sitting at
home with your friends doing absolutely nothing, you can say that you are "just kicking it". This expression is considered to be slang and therefore used only in informal contexts.
Here are a few examples;
*After the exam, my friends and I kicked it at
home last night.
*Some people complain that most government employees go to the office, just kick it back until they have to go
home.
*This expression has more or less the same meaning as "chill out".
*I have a
new foot stool and I'm kicking back tonight with a
cold Leinenkugel.
