Buckle
.I canʹt buckle to. I canʹt give my mind to work. The allusion is to buckling on one’s armour or belt.
To cut the buckle. To caper about, to heel and toe it in dancing. In jigs the two feet buckle or twist into each other with great rapidity.
“Throth, it wouldnʹt lave a laugh in you to see the parson dancinʹ down the road on his way home, and the ministher and methodist, praicher cuttinʹ the buckle as they went along.”—W. B. Yeats: Fairy Tales of the Irish Peasantry, p. 98 (see also p. 196).
“I took a girl to dinner who talked buckle to me.”—Vera. 154.
