Spiced like eggnog passed through by a footballer (9)
I believe the answer is:
nutmegged
'spiced' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives can sometimes define each other.
'like eggnog passed through by a footballer' is the wordplay.
I cannot quite understand how this works, but
'like' could be 'eg' (I've seen this in other clues) and 'eg' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for nutmegged that I've seen before include "hit between the legs" , "embarrassed by passes?" .)
