Odd to be wired badly (5)
I believe the answer is:
weird
'odd' is the definition.
(I've seen this before)
'wired badly' is the wordplay.
'badly' indicates anagramming the letters (letters in the wrong order).
'wired' with letters rearranged gives 'WEIRD'.
'to be' is the link.
(Other definitions for weird that I've seen before include "Quirky" , "Eerie, odd" , "Unearthly" , "Uncanny, bizarre" , "Rum" .)
