Somebody told me that the chick I was hitting on was a vampress.

That girl on Twilight was a real vampress.

2.
A device used for the compression and storage of canned vampires. A highly specialized machine, vampresses generally require a team of four horses (or, in some parts of the world, two male orangutangs) to operate properly.
The vampress saves us heaps of time, compressing the vampires like that.
