Started in Japan, (although probably a lot more well know in america) 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. Not understanding completely, they put it together to come up with a new word for sex that no one else in the school understands.

The teacher put it on his website and from there it spread.
