Endlessly dangerous Romeo up for fun indoors (7,4)
I believe the answer is:
parlour game
'endlessly dangerous romeo' is the definition.
The definition suggests a singular noun which matches the answer.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for parlour game that I've seen before include "bit of fun" , "Glamour pear (anag) - it's played indoors" , "charades, perhaps" , "Eg, Postman's Knock" , "Charades, for example" .)
