personal

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

'insulting a friend' is the definition.
'personal' can be an answer for 'insulting' (thesaurus). I am not sure about the 'a friend' bit.

'wrong senor you put in' is the wordplay.
'wrong' indicates an anagram.
'you put' becomes 'pal' (I can't justify this - if you can you should believe this answer much more).
'in' indicates putting letters inside.
'senor' with letters rearranged gives 'erson'.
'erson' placed inside 'pal' is 'PERSONAL'.

'is' is the link.
