Her Majesty comes back with something boring or something infuriating (3,3)

Ross

I believe the answer is:

red rag

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

'something infuriating' is the definition.
I can't tell whether this defines the answer.

'her majesty comes back with something boring' is the wordplay.
'her majesty' becomes 'ER' (Elizabeth Regina).
'comes back' is a reversal indicator.
'with' means one lot of letters go next to another.
'something boring' becomes 'drag' (I've seen this in another clue).
'er' in reverse letter order is 're'.
're'+'drag'='RED RAG'

'or' is the link.

Can you help me to learn more?

(Other definitions for red rag that I've seen before include "Provocation to bull" , "Something proverbially annoying a bull" , "Bull incitor?" , "Reputed to annoy bull" , "Source of extreme provocation" .)
