'twister' is the definition.
(term for a tornado)

'pulled a con' is the wordplay.
'pulled' becomes 'torn' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'con' becomes 'do' (to 'do' someone could be to con them).
'torn'+'a'+'do'='TORNADO'

Can you help me to learn more?
