Senseless fads? Abominations! (8)
I believe the answer is:
outrages
'abominations' is the definition.
The answer and definition can be both feelings as well as being plural nouns.
Maybe there's an association between them I don't understand?
'senseless fads?' is the wordplay.
'senseless' becomes 'out' (as in unconscious or knocked out).
'fads?' becomes 'rages' ('rage' can be a synonym of 'fad').
'out'+'rages'='OUTRAGES'
Can you help me to learn more?
(Other definitions for outrages that I've seen before include "Scandalises" , "Infuriates" .)
