Get it in the neck over Chinese philosopher's ideal retweet about hothead (6)
I believe the answer is:
throat
'get it in the neck over chinese philosopher's ideal' is the definition.
I can't judge whether this defines the answer.
'retweet about hothead' is the wordplay.
'retweet' becomes 'troat' (I can't explain this - if you can you should give a lot more credence to this answer).
'about' means one lot of letters goes inside another.
'hothead' becomes 'h' (head letter of 'hot').
'troat' enclosing 'h' is 'THROAT'.
Can you help me to learn more?
(Other definitions for throat that I've seen before include "Narrow entrance" , "Forepart of the neck" , "Gorge - frog's location?" , "The pharynx" , "Front part of the neck" .)
