Leaflet covering poor entertainment that kills the buzz (8)
I believe the answer is:
flypaper
'leaflet covering poor entertainment that kills the buzz' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'leaflet covering poor entertainment' is the wordplay.
'leaflet' becomes 'flyer' (I have seen 'Promotional leaflet' mean 'flyer' so perhaps 'leaflet' could also mean 'flyer').
'covering' means one lot of letters goes inside another.
'poor entertainment' becomes 'pap' (I have seen 'mindless entertainment' mean 'pap' so perhaps 'entertainment' could also mean 'pap'. I am not sure about the 'poor' bit.).
'flyer' going around 'pap' is 'FLYPAPER'.
Can you help me to learn more?
(Other definitions for flypaper that I've seen before include "pests will be caught by it" , "one collecting insects" , "should stick to the buzzer" , "Sticky stuff to trap insects" , "Bluebottle catcher" .)
