Librocubicularist

"Miss Chapman, you take the book up with you and read it in bed if you want to. Are you a librocubicularist?" Titania looked a little scandalized. "It's all right, my dear," said Helen. "He only means are you fond of reading in bed. I've been waiting to hear him work that word into the conversation. He made it up, and he's immensely proud if it."

I always smoke an acre of tobacco in bed while reading the most delightful book for all librocubicularists. (I don't think there is such as word as librocubicularist, but Mr. Christopher Morley used it to good advantage in "The Haunted Bookshop" and it has a terrifying sound to the uninitiated ear.)

Ubiquitous as pet owners are, the librocubicularists outnumber them. While dog and cat people can readily be identified by a certain indefinable aura that hovers about them, the "libro" can't be detected until it's too late. […] One night the libro will turn to his loved one and announce that he thinks he will "read for a while." That may well be the beginning of the end. […] The librocubicularist, or reader in bed, should always seek out a mate with the same malady.

To be clear, I don't only read on planes: I'm a librocubicularist. I love reading in bed.
