Cold and slippery (3)
I believe the answer is:
icy
'cold and slippery' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for icy that I've seen before include "(Of relations) very hostile" , "Glacial" , "Freezing and slippy" , "Distant - freezing" , "Very cold, hostile" .)
