Bawling, losing head and interrupting row in intrusive manner (8)

I believe the answer is:

pryingly

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

'bawling losing head and interrupting row' is the definition.
I can't tell whether this defines the answer.

'intrusive manner' is the wordplay.
'intrusive' becomes 'prying' (I've seen this before).
'manner' becomes 'ly' (I can't justify this - if you can you should believe this answer much more).
'prying'+'ly'='PRYINGLY'

'in' acts as a link.

Can you help me to learn more?

I've seen this clue in The Independent.
