Unconventional exit (3-3)
I believe the answer is:
way-out
I believe this is a double definition.
'unconventional' is the first definition.
(I've seen this before)
'exit' is the second definition.
(I know that exit can be written as way out)
(Other definitions for way-out that I've seen before include "Exit, means of egress" , "Exit - eccentric" , "Unconventional; exit" , "Exit - weird" , "Strikingly unconventional" .)
