Get in, as out raising nap (7)
I believe the answer is:
teasing
'raising nap' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'get in as out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'get'+'in'+'as'='getinas'
'getinas' is an anagram of 'TEASING'.
Can you help me to learn more?
(Other definitions for teasing that I've seen before include "Vexing playfully" , "Combing wool and irritating playfully" , "Making fun of (someone)" , "Ribbing" , "Playfully ragging" .)
