Teen nerd squirming after Spitting Image's rude joke? (6,8)
I believe the answer is:
double entendre
'rude joke?' is the definition.
'double entendre' can be an answer for 'joke?' (thesaurus). I am not certain of the 'rude' bit.
'teen nerd squirming after spitting image's' is the wordplay.
'squirming' indicates anagramming the letters (I've seen this in other clues).
'after' is a charade indicator (letters next to each other).
'spitting image' becomes 'double' (both can mean a lookalike).
'teen'+'nerd'='teennerd'
'teennerd' with letters rearranged gives 'entendre'.
'entendre' put after 'double' is 'DOUBLE-ENTENDRE'.
Can you help me to learn more?
(Other definitions for double entendre that I've seen before include "Phrase with two interpretations" , "Nice pun" , "it may be taken as indecent" , "Ambiguous comment" , "Suggestive comment" .)
