'cold shoulder' is the definition.
(I've seen this before)

'east german chauvinism' is the wordplay.
'east german' becomes 'ost' ('east' in German).
'chauvinism' becomes 'racism' (I can't explain this - if you can you should give a lot more credence to this answer).
'ost'+'racism'='OSTRACISM'

'of' acts as a link.

Can you help me to learn more?
