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.

Filling the Cherry

When a girl who is a virgin has sex for the first time with a guy. A piece of skin inside of her vagina is moved once the guy has "put it in". Making her bleed. When your cherry is popped you only bleed the first time. If the man is a virgin as well, this piece of skin is replaced by the foreskin of the man. In this rare occurrence it is possible to pop a girls cherry a second time.

When a virgin man and woman climax at the same time, it is possible for the man to start 'filling the cherry' if the cherry has just popped.
