At first I thought the note was too detailed, but I think it's needed. I've attempted to trim it.

in the The Princeton Dictionary of Buddhism (p 313)
"In Chinese, “dried shit stick,” a CHAN expression attributed to LINJI YIXUAN (d. 867), who dismissed the buddha-nature, or FOXING 
(what he calls the “true man of no rank”; C. WUWEI ZHENREN), as being nothing more than a “dried shit stick"
plenty more on google books, in a 1991 book by Dennis Genpo Merzel for example: "One master when asked, “What is Buddha?” said, “A shit 
stick,”..."

hm. daijs says this is "dried shit in the shape of a stick" "乾いた棒状の糞(くそ)。" but "一説に、くそかきべらで、不浄なもののたとえ。"
daijr and nikk agree: "伝統的にくそかきべらと解されてきたが、本来は乾いた棒状の大便。" "乾いた棒状の糞。誤って、糞を拭うのに用いた乾いたへらと
も解される。"

I'm not really seeing "person attached to the world of appearance" though? daijs says "不浄なもののたとえ。" daijr says "常識的な観念を
打破するため、仏や禅僧の比喩として用いる。" nikk "また、もっともきたないもの、取るに足りないもののたとえに用いられる。"


I know the note is pretty long, but I feel "dried shit stick" should be in there somehow. The other way to format it is maybe having 
3 senses (e.g. 1) sth worthless, 2) stick-shaped shit, 3) dried shit stick), but I don't actually think this would be a better 
solution.

I left that in because it's obviously used a bit and has a Wiki page with that title.
