As dope cut fantastically might become thus? (6,3)
I believe the answer is:
spaced out
'become thus?' is the definition.
I can't tell whether this defines the answer.
'as dope cut fantastically' is the wordplay.
'fantastically' indicates anagramming the letters (a fantastical ordering of the letters).
'as'+'dope'+'cut'='asdopecut'
'asdopecut' anagrammed gives 'SPACED-OUT'.
'might' is the link.
Can you help me to learn more?
(Other definitions for spaced out that I've seen before include "Not quite all there?" , "Disorientated through drugs" , "Separated" , "in a dazed state" , "High on drugs" .)
