Started in Japan. Meaning to have sex, often using a pelvic thrust when doing so.
Caused when a American English teacher told some Japanese kids on a soccer field the English words for waist and shake. So being the kids they are they put it together to come up with a new word for sex that no one really understands outside of the kids...except one guy.

An engrish expression developed by Japanese Pre-teen boys for sexual intercourse. Often used as a two-word sentence to proposition one for sex.

First exposed to Americans by Azrael at http://outpostnine.com/editorials/teacher.html , editorial 51.
"Waist-shake?" the young boy asked his friends, motioning to the cute girl nearby.
"Oh, yes, waist-shake, waist-shake!" his friends replied.

"Waist-shake?" the boy asked the girl. The boy promptly got kicked in the beanbag.
