woobie
 n.— «I don’t actually even know how to spell the word “woobie.” All I know is that the Engineer always used it to mean “a shirt that is really warm and comfortable, but that is in such bad shape that you could never wear it outside your house.”» —“The Woobie” by Gwen Schmidt Library Squirrel (Can.) Nov. 20, 2004.
