Eject every other OK oil cake and yogurt maker (4,3)
I believe the answer is:
kick out
'eject' is the definition.
(synonyms)
'every other ok oil cake and yogurt maker' is the wordplay.
'every other' means one should take alternating letters.
'and' is a charade indicator (letters next to each other).
'yogurt maker' becomes 'out' (I can't justify this - if you can you should give a lot more credence to this answer).
'ok'+'oil'+'cake'='okoilcake'
The alternate letters of 'okoilcake' are 'kick'.
'kick'+'out'='KICK OUT'
Can you help me to learn more?
(Other definitions for kick out that I've seen before include "Lash with foot; expel" , "Expel using boot" .)
