Her Majesty turned up with something boring or something infuriating (3,3)
I believe the answer is:
red rag
'something infuriating' is the definition.
I can't judge whether this defines the answer.
'her majesty turned up with something boring' is the wordplay.
'her majesty' becomes 'ER' (Elizabeth Regina).
'turned up' shows that the letters should be reversed in order.
'with' says to put letters next to each other.
'something boring' becomes 'drag' (I've seen this in another clue).
'er' written backwards gives '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" , "Proverbial bull enrager" , "Something proverbially annoying a bull" , "might attract a charge" , "Reputed to annoy bull" .)
