I thought this stone got its name from the fact that it looks a bit like a nose (as in ‘keep yer neb out’ = stop being nosey). Apparently it is a Yorkshire term meaning ‘to kiss’, Paul Bennett say in ‘Circles, Standing Stones and legendary rocks of West Yorkshire’ that lovers used to meet to hold their trysts here.
‘Nose’ and ‘kiss’ are both convincing derivations for the name. From the Swastika Stone or nearby, about half a mile northwest, it looks like a sharp nose silhouetted against the skyline. And also appears to ’kiss’ the hillside above it. (Sorry, didn’t take a photo - next time!)
