Had fun making love in a vehicle, second-hand (8)
I believe the answer is:
caroused
'had fun' is the definition.
The answer and definition can be both to do with social activities as well as being past participle verbs.
Maybe you can see a link between them that I don't see?
'love in a vehicle second-hand' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'in' is an insertion indicator.
'a vehicle' becomes 'car' (car is a kind of vehicle).
'second hand' becomes 'used' (second hand can mean previously owned or used).
'car'+'used'='carused'
'o' put inside 'carused' is 'CAROUSED'.
'making' is the link.
Can you help me to learn more?
(Other definitions for caroused that I've seen before include "Partied noisily" , "Revelled" , "Enjoyed oneself in a noisy, lively way" .)
