Down second flipping hot drink (6)
I believe the answer is:
mopish
'down' is the definition.
Both the definition and answer are adjectives.
Perhaps they are linked in a way I don't understand?
'second flipping hot drink' is the wordplay.
'second' becomes 'mo' (both are short periods of time).
'flipping' says the letters should be written in reverse.
'hot' becomes 'h' (common abbreviation eg on taps).
'drink' becomes 'sip' (sipping is a kind of drinking).
'h'+'sip'='hsip'
'hsip' written backwards gives 'pish'.
'mo'+'pish'='MOPISH'
Can you help me to learn more?
(Other definitions for mopish that I've seen before include "Somewhat depressed" , "Listless" , "dejected" , "down in the dumps" , "low on spirits" .)
