(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!

A heterosexual man who attempts to portray a metrosexual image, yet fails considerably, because of his poor fashion, hairstyle, and grooming choices. He is usually from a bridge and tunnel area outside of a major metropolitan area. His fashion is usually outdated and his clothes sometimes contain fake brand names. He is usually in decent shape, but his clothes accentuate all of the unattractive body parts that he thinks look fantastic. He usually uses a lot of product in his hair which is very noticeable to the human eye.
The guys from Jersey Shore are pretty, but they're totally Bridge and Tunnel Metro (BTM).
