Gathering English rap covers showing culture (3,5)
I believe the answer is:
tea party
'gathering' is the definition.
(tea party is a kind of gathering)
'english rap covers showing culture' is the wordplay.
'english' becomes 'e' (abbreviation).
'rap' becomes 'tap' (synonyms).
'covers' is an insertion indicator.
'showing culture' becomes 'arty' (I can't justify this - if you can you should believe this answer much more).
'e' going within 'tap' is 'teap'.
'teap'+'arty'='TEA-PARTY'
Can you help me to learn more?
(Other definitions for tea party that I've seen before include "Social gathering (for Bostonians?)" , "Sober occasion" , "Function 22 attended" , "The Mad Hatter held one" , "sort of celebration" .)
