Terribly short! Slice a few directly? (2,3,4,5)
I believe the answer is:
as the crow flies
'directly?' is the definition.
(as the crow flies means in a direct route)
'terribly short slice a few' is the wordplay.
'terribly' indicates an anagram.
'short'+'slice'+'a'+'few'='shortsliceafew'
'shortsliceafew' anagrammed gives 'AS THE CROW FLIES'.
(Other definitions for as the crow flies that I've seen before include "move in a straight line" , "By direct route" , "without deviating" , "taking shortest route" , "How rook moves" .)
