Parisian's bed? Out of it is out of it (3,2)
I believe the answer is:
lit up
'it is out of it' is the definition.
(both can mean drunk)
'parisian's bed? out' is the wordplay.
I cannot quite see how this works, but
'parisian's bed?' could be 'lit' ('bed' in French) and 'lit' is located in the answer.
The remaining letters 'up' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'of' is the link.
(Other definitions for lit up that I've seen before include "Flashing" , "high" , "Started smoking - being drugged!" , "Prepared to smoke" , "Illuminated (by drink or drugs?)" .)
