Liver math is the calculation(s) you make throughout the night to help determine if you are sober enough to drive home.
Alcohol is processed by the body at a determined rate (generally one beer/shot/wine glass an hour), and you can save yourself a night in the drunk tank and some legal fees by adhering to liver math.
Liver math or cab fare. Either is a wise choice. Disregard at your own peril.

It is associated with basic/rough figures traditionally done on the back of a beer coaster at a pub while drinking.
An example might be mates working out the cost of a fishing trip, so "Fuel will be about $100, bait about $50, accom about $200 and good about $200". So rough/approximate figures.
According to my beer coaster maths, it would be about $500. But if you want a more accurate number I'd obviously have to look it up, speak to the suppliers etc.
