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.

Coffee Filtration 

When one sucks off another, then as male is about to ejaculate, he states his predicament to the partner who promptly places a thin layer of material, i.e undergarments, over the penis. At this point, said sucker places mouth around partners penis. The penis holder then spurts his 'sex wee' through material. Sucker then sucks semen through material causing filtration. Pleasure ensues.

fellratio

Quantitative description of the balance between knob-polishing (KP) and rug munching (RM) in a long-term relationship; fellratio (FR) = KP/RM. All other predictors of relationship stability considered, an FR > 2 or < .5 is considered a serious red flag.

Fred had become increasingly shut off from Wilma emotionally, and the fellratio of .1 went a long way toward explaining this distancing.
