The last of the great "metal rushes" of the 19th century, from 1897-1899. Notable for occuring in the hostile, subarctic region of the Yukon Territory and parts of Alaska.
The gold rush was immortalized through works of fiction such as The Call of the Wild by Jack London and equally as much by Charlie Chaplin eating his shoe in a skit about it.
While having sex, the girl hangs over the edge of the bed until she is basically standing on her head. Then the man, while on his knees on the bed, begins to ram her hard. While doing this, he is leaning forward and making arm motions and "koosh" sounds as if skiing in the klondike. Really skanky thing to do.
I really want to go skiing, but since it's July, I'll have to settle for the Klondike Koosh.
