fetid

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

'smelling bad' is the definition.
'fetid' can be an answer for 'bad' (thesaurus). I'm not certain of the 'smelling' bit.

'it's wrong to be fed out' is the wordplay.
'wrong' indicates anagramming the letters.
'to be fed' indicates putting letters inside.
'out' becomes 'fed' (I can't justify this - if you can you should believe this answer much more).
'it' is an anagram of 'ti'.
'ti' placed within 'fed' is 'FETID'.

'when' acts as a link.
