Bother! It's a man-hole! (2-2)
I believe the answer is:
to-do
'bother' is the definition.
(I've seen this before)
'a man-hole' is the wordplay.
'a man' becomes 'tod' ().
'hole' becomes 'O' (O looks like a hole).
'tod'+'o'='TO-DO'
'it's' acts as a link.
(Other definitions for to-do that I've seen before include "Quarrel" , "Bustle" , "Kerfuffle" , "Fuss and bother" , "Spot of bother" .)
