Brownies
Brownies were originally pixie-like creatures who became the female version of Cub scouts[?] in Britain, or the younger version of Guides. They are divided into packs with names such as Leprechauns, Pixies[?] and so on. As Britain now allows girls to join the Cubs (like America) Brownies are dying out.
"To be chucked out of the Brownies" is a punishment that never takes place, a fake threat.
"Good Brownie points" means that it is in your interest to do something.
Despite Brownies dying out, the above phrases are still used in British English.
