Tweet reflection of gym class (4)
I believe the answer is:
peep
This clue could be a double definition.
'tweet' is the first definition.
(thesaurus)
'reflection of gym class' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for peep that I've seen before include "Look furtively (in both directions)" , "Look surreptitiously - through a keyhole?" , "Look secretly" , "Look slyly" , "Sly look (palindrome)" .)
