chicken head
n.— «While cleaning the nut Mutt[0] had placed where the climb goes back into the corner, I’m thinking “Man, I’m glad I didn’t lead that pitch, very airy and a nasty fall onto plate sized chicken heads.”…We can’t let it trail down since it could easily get caught on plentiful knobs and chicken heads on the face.» —“TR: Gumbies, Geezers and the Hard Truth” Usenet: rec.climbing July 3, 2001.
