(short for boobs-to-maintenance ratio) is a commonly used metric for gold-diggers, pioneered by bitcoin millionaires and Hong Kong veterans.

Units: cup (A = 1, B = 2, etc...) per $1000 of monthly maintenance cost.

Anything with BTM ration of 4 or above is considered a good investment. The ultimate goal in life is to father children with women who have an infinite BTM ratio.
1. My Thai GF got a BTM ratio of 8, what a catch!

2. Hong Kong's average BTM ratio is 0.5, no wonder the country's falling apart!

Running for exercise and picking up trash you find along the way. It's good for the body, mind, soul, and environment! Started in Sweden but is making its way to the U. S.
It's nice out and the city is filthy. Let's go plogging!
