Is there a formula for getting drunk?!

NO

Body weight has no effect on how your body can deal with alcohol - What is does have an effect on is when you are "legally considered drunk", the heavier you are the more blood you have so the more alcohol you can absorb before reaching a certain BAC level.

But this is not what I consider as "getting drunk", I consider "getting drunk" to mean when you start to feel the effects of the alcohol.

Metabolism can affect how you recover, but not how fast you will get drunk to any noticeable level

PS:

The person with the 12oz/hour for beer etc in their post is talking about how fast your body deals with alcohol.

That has nothing to do with how fast you get drunk, but how fast you can sober up.

How fast you get drunk, assuming you mean feeel the effects of alcohol, depends on your natural alcohol tolerance and not anything arbitrary like height & weight.

(mass(# of drinks))/time- (12oz/hr)= level

12oz/hr is beer ,8oz per hr wine, 1 oz per hr liquor

Basic formula for getting drunk is "stupid"

Drink+Drink=Drunk

xy - cd equals pi$$ed where c is BMI.
