European, spaced out, flew the coop (7)
I believe the answer is:
escaped
'flew the coop' is the definition.
(I've seen this in another clue)
'european spaced out' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'spaced' is an anagram of 'scaped'.
'e'+'scaped'='ESCAPED'
(Other definitions for escaped that I've seen before include "Got away, broke loose" , "Broke free, got away" , "Ran away from confinement" , "Got away from captors" , "Fled from captivity" .)
