Shabby party ready to roll? (3-5)
I believe the answer is:
dog-eared
But I can't explain it at all!
(Other definitions for dog-eared that I've seen before include "Of book, with pages crumpled at the corners" , "Of book, with pages turned down at corners" , "(Of pages) having corners turned down or worn" , "Of book, having page corners turned down" , "Shabby with corners of pages turned down" .)
