Pants of a friend suspended by shower? (6,3)
I believe the answer is:
rained off
'suspended by shower?' is the definition.
'pants of a friend' is the wordplay.
'pants' is an anagram indicator (UK informal term for 'nonsense' or 'rubbish').
'of'+'a'+'friend'='ofafriend'
'ofafriend' with letters rearranged gives 'RAINED OFF'.
(Other definitions for rained off that I've seen before include "Delayed" , "cancelled due to weather" , "Ended by bad weather" .)
