I'm a little stuck... Click here to teach me more about this clue!

'an angry man' is the definition.
The definition suggests a singular noun which matches the answer.

'having slept poorly after hard liquor i left skint broke' is the wordplay.
I cannot quite see how this works, but
an anagram of 'slept' is 'pelst' which is located in the answer.
'liquor' could be 'rum' (rum is a kind of liquor) and 'rum' is found in the answer.
'i' is within the answer.
'left' could be 'l' (common abbreviation) and 'l' is present in the answer.
an anagram of 'skint' is 'tskin' which is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
