Eccentric exit? (3,3)
I believe the answer is:
way out
I believe this clue is a double definition.
'eccentric' is the first definition.
(I've seen this before)
'exit?' is the second definition.
('way out' can be a synonym of 'exit')
(Other definitions for way out that I've seen before include "Unconventional - exit" , "Exit - eccentric" , "Exit - weird" , "Hit wicket, for example" , "Extremely unconventional" .)
