Mock food rations (5)
I believe the answer is:
scoff
I believe this is a triple definition!
'mock' is the first definition.
(scoff can mean to mock or tease)
'food' is the second definition.
(I've seen this before)
'rations' is the third definition.
(thesaurus)
(Other definitions for scoff that I've seen before include "Mock" , "Devour (informal)" , "Speak scornfully; eat" , "Deride - guzzle" , "Furiously swallow" .)
