Huh. Well yeah I never knew that either, growing up in the South that was a pretty common saying with a similar spelling to how I wrote it originally(being the south the misspelling makes total sense now haha). Nice to know where it comes from though. Thanks for the info!

It’s an American saying, basically meaning a lot of money in this case. You can use bookoo to mean a lot of any thing really.

ON the toilet? Not in it???
