Cocktail, Crete tea and the rest (2,6)
I believe the answer is:
et cetera
'and the rest' is the definition.
(I've seen this before)
'cocktail crete tea' is the wordplay.
'cocktail' indicates an anagram.
'crete'+'tea'='cretetea'
'cretetea' anagrammed gives 'ET CETERA'.
(Other definitions for et cetera that I've seen before include "and the others" , "something similar" , "And similar things" , "And the rest (Latin)" , "Drive out, expel" .)
