Ape risks ruining social activities (5,3)
I believe the answer is:
apres ski
'ape risks ruining social activities' is the definition.
I can't tell whether this definition defines the answer.
'ape risks ruining' is the wordplay.
'ruining' indicates an anagram.
'ape'+'risks'='aperisks'
'aperisks' is an anagram of 'APRES-SKI'.
Can you help me to learn more?
(Other definitions for apres ski that I've seen before include "activity at Klosters?" , "activity in the Alps" , "As social activity" , "social occasion" , "Mountain fun perhaps" .)
