King casually calls for toast with pork pie (7)
I believe the answer is:
charlie
'king casually calls' is the definition.
I can't judge whether this definition defines the answer.
'toast with pork pie' is the wordplay.
'toast' becomes 'char' (I've seen this in another clue).
'with' means one lot of letters go next to another.
'pork pie' becomes 'lie' ('pork pie' is Cockney rhyming slang for a lie).
'char'+'lie'='CHARLIE'
'for' is the link.
Can you help me to learn more?
(Other definitions for charlie that I've seen before include "-- Chaplin" , "Cocaine (colloq.), fool (colloq.)" , "Fool; man's name" , "Code word < for silly fellow" , "Silly person" .)
