Brownie point

also brownie point
n.
An amount of credit considered as earned, especially by favorably impressing a superior. Often used in the plural.

[From the practice of awarding points for achievement to Brownies in the Girl Scouts.]

Credit for a good deed, as in John earned a lot of brownie points for doing his boss's report for him. The term originated with the points earned for various achievements by the youngest group of the Girl Scouts, called Brownies. In the mid-1900s it was transferred to general use.
