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

'expert in smut' is the definition.
The definition suggests a singular noun which matches the answer.

'mostly i go dancing around clubs' is the wordplay.
'dancing' indicates an anagram.
'around' is an insertion indicator.
'clubs' becomes 'c' (abbreviation in card games).
'mostly'+'i'+'go'='mostlyigo'
'mostlyigo' with letters rearranged gives 'myologist'.
'myologist' going around 'c' is 'MYCOLOGIST'.

'say' is the link.
