Go to meet German girl somewhere for a little drink? (4,5)

'a little drink?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.

'go to meet german girl somewhere' is the wordplay.
I cannot quite see how this works, but
'go' could be 'shot' (I've seen this before) and 'shot' is found within the answer.
'german' could be 'g' (abbreviation) and 'g' is located in the answer.
'girl' could be 'lass' (lass can informally mean a girl) and 'lass' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

'for' is the link.

Can you help me to learn more?
