'celebrity' is the definition.
(celebrity can mean fame or stardom)

'group of defenders bother stuck up' is the wordplay.
'group of defenders' becomes 'mod' (I can't explain this - if you can you should give a lot more credence to this answer).
'bother' becomes 'rats' (both are expressions of annoyance).
'stuck up' says the letters should be written backwards.
'mod'+'rats'='modrats'
'modrats' reversed gives 'STARDOM'.

(Other definitions for stardom that I've seen before include "wide renown" , "(The prestige of) celebrity" , "Great fame" , "Stage or screen fame" , "Great celebrity" .)
