Drinks up, goes for a drive (4)
I believe the answer is:
spin
'for a drive' is the definition.
(I've seen this before)
'drinks up' is the wordplay.
'drinks' becomes 'nips' (miniature drink bottles).
'up' is a reversal indicator (in down clue: letters go upwards).
'nips' in reverse letter order is 'SPIN'.
'goes' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for spin that I've seen before include "Rotate repeatedly" , "Short drive" , "Rotate; ride" , "Gyrate, reel" , "Political bias" .)
