noisier

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

'getting extra rowdy' is the definition.
I can't tell whether this definition defines the answer.

'more inquisitive about one' is the wordplay.
'more inquisitive' becomes 'nosier' (nosy means overly inquisitive or curious).
'about' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'nosier' placed around 'i' is 'NOISIER'.

Can you help me to learn more?

(Other definitions for noisier that I've seen before include "more deafening!" , "More loud" , "Less quiet" , "Perhaps more disturbing" , "More of a racket" .)
