Justine: yes okay
Jeff: yes I'm hungry before the night out. Please save me a piece

Semen that is pleasant to taste, easier to swallow, sweeter and less bitter than regular cum which is sour, most likely spit out, or used to lubricate other parts of the body. It can also be used to describe any one who looks tasty, sexy, attractive, edible, lick-able.
