Drive empty Bugatti into swimming pool (6)
I believe the answer is:
libido
'drive' is the definition.
(I've seen this before)
'empty bugatti into swimming pool' is the wordplay.
'empty' says to hollow out the word (remove centre letters).
'into' indicates putting letters inside.
'swimming pool' becomes 'lido' (lido is a type of open-air swimming pool).
'bugatti' with its centre taken out is 'bi'.
'bi' inserted inside 'lido' is 'LIBIDO'.
(Other definitions for libido that I've seen before include "Freud's sex drive" , "Natural urges" , "Sexual impulse" , "Sexual or psychological urge" , "Emotional craving" .)
