Very wrong to drink drop of Glenfiddich, a couple of fingers (1-4)
I believe the answer is:
v-sign
'a couple of fingers' is the definition.
I can't judge whether this defines the answer.
'very wrong to drink drop of glenfiddich' is the wordplay.
'very' becomes 'v' (abbreviation).
'wrong' becomes 'sin' (wrong can mean a sin or crime).
'to drink' means one lot of letters goes inside another.
'drop of' suggests taking the first letters (the smallest possible amount of the word).
The first letter of 'glenfiddich' is 'g'.
'sin' going around 'g' is 'sign'.
'v'+'sign'='V-SIGN'
Can you help me to learn more?
(Other definitions for v-sign that I've seen before include "number 5 for Julius Caesar" , "Gesture (from Winston or Harvey?)" , "Offensive gesture" , "Victory token" .)
