Drink and hot dog after spending penny (5)
I believe the answer is:
hooch
'drink' is the definition.
(hooch is a kind of drink)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for hooch that I've seen before include "alcoholic drink" , "Illicit alcohol" , "banned alcohol" , "Illicit spirits" , "Strong illicit liquor" .)
