Kinky weirdo shall reach 50s - expect consequences! (5,4,4)
I believe the answer is:
heads will roll
'50s expect consequences' is the definition.
I know nothing about this answer so I can't judge whether this works.
'kinky weirdo shall reach' is the wordplay.
'kinky' indicates an anagram.
'reach' becomes 'll' (I am not sure about this - if you are sure you should believe this answer much more).
'weirdo'+'shall'='weirdoshall'
'weirdoshall' with letters rearranged gives 'headswillro'.
'headswillro'+'ll'='HEADS WILL ROLL'
Can you help me to learn more?
(Other definitions for heads will roll that I've seen before include ""Some of you will be fired for this!"" , "People are going to carry the can" , "Someone will have to pay for this!" , "People will be dismissed" , "People are going to pay for this!" .)
