darn

I'm a little stuck... Click here to teach me more about this clue!

'man' is the definition.

I cannot understand how the remainder of the clue works.

(Other definitions for darn that I've seen before include "Mend (e.g. socks)" , "Repair holes by sewing" , "Mend with a needle" , "curse" , "Repair by sewing, socks perhaps" .)

I've seen this clue in The Telegraph.
