What it means
A jokey label for the bent little logic some men use to sell themselves a daft decision. Stuff like spending way more to save a tiny bit, calling an expensive gadget an investment, or adding a cheeky inch or two to their height. It’s usually said tongue in cheek, not deep or serious.
Usage examples
"He drove forty minutes to save two pounds on petrol, pure boy math."
"Counting the gym membership he never uses as being healthy is boy math."
"Buying a £300 barbecue so he can stop paying for takeaways once a month is peak boy math."
"Saying the fishing rod basically paid for itself after one decent catch is absolute boy math."

Where it comes from
It popped up online as a playful counterpart to girl math, which was already doing the rounds on TikTok and other social apps in 2023. People started calling out the equally dodgy logic lads use on money, gadgets, sport, cars, and ego, then the phrase spread fast into everyday banter.
