A song from the Radiohead album,(1995) The Bends. It is about a world of fake people, things that are not real and people that don't know why, they do what they do, as well to me it's about trying to be in love with someone that is not in love with you there fake not real. you are in love with I idea of them and that's why it feels fake.
"She looks like the real thing, She tastes like the real thing, My fake plastic love."
Fake Plastic Trees: when you get what you want, but not what you need.
