'putting the lid on the whisky?' is the definition.
I can't tell whether this defines the answer.

'putting the lid on the whisky?' is the wordplay.
'putting the lid' becomes 'ing' (I can't justify this - if you can you should believe this answer much more).
'on' means one lot of letters go next to another.
'the whisky?' becomes 'scotch' (Scotch is an example).
'ing' put after 'scotch' is 'SCOTCHING'.
