Dummy spit?

I was just joking with my Swedish-Australian buddy, and I told her that I've had enough, and I'm gonna pick up my bat n ball & go home. She didn't understand.

I'm laying odds this originated from cricket - but does anyone now?

This means 'pick up your things and go home'?


Yes, it's sort of a dummy spit. ie. I don't want to play any more, or I don't want to do this any more.

Lap; What's a dummy spit?
