In the lyrics of the song "Far Away Eyes" by the Rolling Stones it is said:
I had an arrangement to meet a girl, and I was kind of late
And I thought by the time I got there she'd be off
She'd be off with the nearest truck driver she could find
Much to my surprise, there she was sittin' in the corner
A little bleary, worse for wear and tear
Was a girl with far away eyes
I researched the meaning of the expression "worse for wear and tear" and found the following:
Origin of Worse for Wear
This translates into as things are used, they wear and deteriorate. After worse for wear became a popular expression, a new expression came about: none worse for the wear, meaning used but not worn out. Similar expressions to worse for wear are worn out and wear and tear.
I can't understand how this type of adjective applies to a person, in this case the girl mentioned in the song. As far as I can understand it seems to be appropriate if you're talking about clothes, shoes, etc., but I can't decipher what it could mean in relation to a person.
In fact the entire phrase "A little bleary, worse for wear and tear" sounds confusing or unclear to me, including what the actual meaning of the expression "a little bleary" could be.
