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

'uncontrollable kid?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'teen brat joins rn life changing' is the wordplay.
'joins' says to put letters next to each other.
'changing' is an anagram indicator.
'teen' put after 'brat' is 'bratteen'.
'bratteen'+'rn'+'life'='bratteenrnlife'
'bratteenrnlife' with letters rearranged gives 'ENFANT TERRIBLE'.
