Tasteless items of jewellery? A couple mentioned in rap (6)
I believe the answer is:
tattoo
'rap' is the definition.
(thesaurus)
'tasteless items of jewellery? a couple mentioned' is the wordplay.
'tasteless items of jewellery?' becomes 'tat'.
'a couple' becomes 'two' (I've seen this before).
'mentioned' shows a homophone (sound like).
'two' is a homophone of 'too'.
'tat'+'too'='TATTOO'
'in' acts as a link.
(Other definitions for tattoo that I've seen before include "signal to return to base" , "Military display - picture on the skin" , "Indelible picture made in the skin" , "Edinburgh military parade" , "Edinburgh show" .)
