Definition
Humorous, loosely-reasoned financial logic that justifies spending or saving money through creative (and often illogical) rationalization. Common examples include considering money spent on sale items as money saved, or justifying expensive purchases because they'll be used frequently.
Example Usage
Girl math: I spent $200 on shoes, but they were 30% off, so technically I saved $86.
Origin
Emerged from TikTok and social media in 2022 as a tongue-in-cheek take on informal personal finance reasoning, often gendered humorously.
Fun Fact
The term is self-aware satire that critiques actual financial reasoning many people use; it's become a meme celebrating illogical but relatable spending habits.
