Stephen King used this descriptor in The Green Mile, which I read this week. I was all, “Really? Painfully thin? Are you sure?” But I imagine that someone who has written as many millions of words as King has must run out of modifiers at some point.
Interestingly, he followed painfully thin with a less-cliched description that could’ve replaced it altogether, something like, “He was painfully thin, as if recovering from a long illness.” I have to admit I forgave his placement of the overused modifier upon reading the long illness part.
