Comment made when contemptuous lout grabs bishop (3-3)
I believe the answer is:
yah-boo
'comment made when contemptuous' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'lout grabs bishop' is the wordplay.
'lout' becomes 'yahoo' (I've seen this in another clue).
'grabs' is an insertion indicator.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'yahoo' going around 'b' is 'YAH-BOO'.
Can you help me to learn more?
(Another definition for yah-boo that I've seen is " Derisive exclamation".)
