Party can become pear-shaped with sloppy kiss (5-3)
I believe the answer is:
apres-ski
'party can' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I can't see?
'pear-shaped with sloppy kiss' is the wordplay.
'shaped' is an anagram indicator.
'with' says to put letters next to each other.
'sloppy' is an anagram indicator.
'pear' is an anagram of 'apre'.
'kiss' is an anagram of 'sski'.
'apre'+'sski'='APRES-SKI'
'become' is the link.
Can you help me to learn more?
(Other definitions for apres-ski that I've seen before include "Winter sports social" , "Socialising after winter sport" , "party activity" , "Party following winter sports" , "Nightlife after going on the piste" .)
