Falsified dumper put out of order (7,2)
I believe the answer is:
trumped up
'out of order' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'falsified dumper put' is the wordplay.
'falsified' indicates an anagram.
'dumper'+'put'='dumperput'
'dumperput' anagrammed gives 'TRUMPED-UP'.
Can you help me to learn more?
(Other definitions for trumped up that I've seen before include "Concocted with intent to deceive" , "Concocted, charges perhaps" , "Fake" , "not properly designed" , "Invented as an excuse or a false accusation" .)
