Irrational justification of spending.
My matcha was free this morning because I paid in cash, girl math.
The term "girl math" began to gain popularity after user Samantha Jane posted a TikTok where she jokingly justified her spending habits. Following her video, people began to stitch, duet, or create their own videos using the term, each with their own humorous justifications for spending. While the term originally focused on spending money, it has since expanded to describe various lifestyle decisions and rationalizations in a light-hearted manner.
Examples of "girl math" include the following: Returning an item for the original value means you earned money, calories don't count on vacation, and anything under $5 doesn’t count. These humorous interpretations of "math" are not meant to be taken seriously but rather highlight the playful ways people pardon their choices.
