Encourage to throw a drink (3,4)

I believe the answer is:

egg flip

'a drink' is the definition.
(I've seen this before)

'encourage to throw' is the wordplay.
'encourage' becomes 'egg'.
'to throw' becomes 'flip' ('flip' can be a synonym of 'throw').
'egg'+'flip'='EGG-FLIP'

(Another definition for egg flip that I've seen is " Alcoholic drink".)

I've seen this clue in The Irish Independent.
