A punch in the mouth for Sonic's friend with timeless sorceress (7,8)
I believe the answer is:
knuckle sandwich
'a punch in the mouth' is the definition.
(I've seen this in another clue)
'sonic's friend with timeless sorceress' is the wordplay.
I cannot quite understand how this works, but
'with' could be 'and' and 'and' is located in the answer.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for knuckle sandwich that I've seen before include "Buffet" , "Slug" , "Punch in mug" , "hit" , "piece of pork between slices of bread" .)
