Girl who eats like a bird, but drinks like a fish. Don't be fooled by her minimal appetite, she is not a cheap date as she can consume up to 10 long islands in one sitting. On the upscale fish-birds generally put out as they do love to fuck.
That girl barely eats but she drinks like a fucking fishbird.
