Embarrassed-looking nincompoop back in dating app (6)
I believe the answer is:
tinder
'dating app' is the definition.
(I know that Tinder is a dating app)
'embarrassed-looking nincompoop back' is the wordplay.
'embarrassed-looking' becomes 'red' (I've seen this in another clue).
'nincompoop' becomes 'nit' (I am not sure about this - if you are sure you should believe this answer much more).
'back' says the letters should be written backwards.
'red'+'nit'='rednit'
'rednit' written backwards gives 'TINDER'.
'in' is the link.
Can you help me to learn more?
(Other definitions for tinder that I've seen before include "Stuff that lights easily, good to start fire" , "Dry material for starting fire" , "Dry stuff that fires easily" , "Dry stuff for starting fire" , "Dry material for starting fires" .)
