Host drinks wine, sticky stuff (6)
I believe the answer is:
mastic
'sticky stuff' is the definition.
'mastic' can be an answer for 'stuff' (mastic is a kind of stuff). I'm not sure about the 'sticky' bit.
'host drinks wine' is the wordplay.
'host' becomes 'mc' (short for Master of Ceremonies).
'drinks' means one lot of letters goes inside another (inserted letters are consumed or drunk).
'wine' becomes 'asti' (Italian wine).
'mc' going around 'asti' is 'MASTIC'.
Can you help me to learn more?
(Other definitions for mastic that I've seen before include "Mac, sit and produce a gum resin" , "Gum from trees" , "Putty-like cement used as adhesive or filler" , "Substance applied to joints" , "Aromatic resin used to make varnish" .)
