Revolutionary chat after extra time and one could end up in hot water (3,3)
I believe the answer is:
tea bag
'one could end up in hot water' is the definition.
I can't tell whether this definition defines the answer.
'revolutionary chat after extra time' is the wordplay.
'revolutionary' says the letters should be written in reverse.
'chat' becomes 'gab' (gab is a kind of chat).
'after extra time' becomes 'aet' (this might be a standard abbreviation which I don't know about).
'gab'+'aet'='gabaet'
'gabaet' backwards is 'TEA-BAG'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for tea bag that I've seen before include "Ingredient of a brew-up" , "Cuppa maker" , "Sachet for infusion" , "Sachet to put in pot" , "Age bat (anag.)" .)
