Girls get involved with men - troublemakers (8)
I believe the answer is:
gremlins
'troublemakers' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'girls get involved with men' is the wordplay.
'get involved with' indicates anagramming the letters.
'girls' anagrammed with 'men' makes 'GREMLINS'.
Can you help me to learn more?
(Other definitions for gremlins that I've seen before include "Mischievous sprites responsible for mechanical problems" , "Mischievous sprites, maybe in machinery" .)
