Toast from part of Asia cut twice (4-4)
I believe the answer is:
chin-chin
'toast' is the definition.
(I've seen this before)
'part of asia cut twice' is the wordplay.
'part of asia cut' becomes 'chin' (I am not sure about this - if you are sure you should believe this answer much more).
'twice' says to double the letters.
'chin' doubled is 'CHIN-CHIN'.
'from' is the link.
Can you help me to learn more?
(Other definitions for chin-chin that I've seen before include "Down the hatch!" , "good health ..." , "Cheers, bottoms up" .)
