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.

city chicken 

A food native to Pittsburgh/Western Pennsylvania in which cubes of pork and/or veal are put on a short, wooden skewer, breaded, then baked and/or fried.

I've heard that city chicken originated during the Great Depression, when folks didn't have enough money to buy full cuts of meat, so they assembled meat scraps on a wooden skewer, creating a make-shift drumstick. Hence the name.
Are yinz havin' city chicken for dinner?

endwarfins

The rush of neurotransmitters and neuropeptides triggered specifically by watching the Seven Dwarfs march home singing "Heigh-Ho" — that particular high of pickaxes, whistling while you work, and communal domestic bliss in a cottage built for men half your height.
I only meant to watch the Heigh-Ho scene for the endwarfins, and then it was two hours later and I'd watched the whole movie.

Endwarfins aren't just a Snow White thing — I get the same hit off the Lollipop Guild in Oz.
