Drink beer to get half out of it? Wicked! (5)
I believe the answer is:
super
'wicked' is the definition.
(I've seen this before)
'drink beer to get half out of it?' is the wordplay.
I cannot quite see how this works, but
'drink' could be 'sup' (to sup is to drink) and 'sup' is present in the answer.
'it?' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found in the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for super that I've seen before include "Excellent - small-part actor" , "Excellent; policeman" , "Delightful" , "Incomparable" , "Prefix meaning terrific or great" .)
