Fill-ratio 

When you are out to eat at a restaurant that has free refills on your drink. If your server keeps your glass full, the server has a high fill-ratio. If the server ignores you and leaves you thirsty, the server has a low fill-ratio.

A takeoff of “kill-ratio”

Our waiter’s fill-ratio is pathetic—he hasn’t come by once.

Mythical Ratio 

The ratio between any two different mythical creatures, weapons, items, or persons.
This ratio is calculated by dividing the weapon, person, or creature's kills or lives saved by one hundred.

The mythical ratio of Thor's hammer is blah blah blah.

merkshire ratio

The ratio of time it takes one to pack a bowl and the time it takes for said person to actually hit the bowl. The longer you sit with a packed bowl, the higher the ratio becomes.

- Yo Joel, are you gonna hit that?

- Yeah, yeah.. sorry, just was watching something on my phone
- bro, you’re merkshiring really hard right now. And your merkshire ratio is incredibly high, please be cognizant.

eye-to-bag ratio 

Eye-to-bag ratio, symbol ξ, is defined such that

ξ = h(eye)/h(eye bag) = k*beauty

where h is a function of height,
h(eye) is the height of an individual's open eye,
h(eye bag) is the visible height of the eye bag, and

k is a nonzero arbitrary constant. Rearranging the equation gives:

beauty ∝ξ

Evidence suggests that when
- h(eye) is high and/or
- h(eye bag) is low,
ξ (eye-to-bag ratio) is large and thus, under a constant k condition, beauty of the individual yielding the calculated ξ is also large.
