'most inebriated' is the definition.
Both the definition and answer are superlative adjectives. Maybe there's a link between them I don't understand?

'heads of the interns' dorms dance lewdly irritating every single teacher' is the wordplay.
'heads of' says to take the initial letters.
'irritating every single teacher' becomes 'iest' (this might be a standard abbreviation of which I'm unaware).
The initial letters of 'the interns dorms dance lewdly' is 'tiddl'.
'tiddl'+'iest'='TIDDLIEST'
