perhaps from Old French bafe baffe ‘blow with the back of the hand’ a word which survives as a dialect term in modern Normandy and Picardy. For the sense compare Dunt and Dash .perhaps also a variant of Boff (see Bough ) with unrounding of [o] to [a] although this would not account for the medieval evidence in Hants. Compare Baffin and Boffin .
