Boozy drink for one grand? Lose it (3,4)
I believe the answer is:
egg flip
'boozy drink' is the definition.
'egg flip' can be an answer for 'drink' (I've seen this before). I'm not certain of the 'boozy' bit.
'for one grand? lose it' is the wordplay.
'for one' becomes 'eg' (both can mean 'for example').
'grand?' becomes 'G' (G is short for grand as in a thousand).
'lose it' becomes 'flip' (both can mean to become very angry suddenly).
'eg'+'g'+'flip'='EGG-FLIP'
Can you help me to learn more?
(Another definition for egg flip that I've seen is " Alcoholic drink".)
