'felix is happy in it' is the definition.
I can't judge whether this defines the answer.

'felix is happy in it' is the wordplay.
'felix' becomes 'la' (I can't explain this - if you can you should believe this answer much more).
'is happy' is an anagram indicator (happy can mean slightly drunk).
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'in'+'t'='int'
'int' with letters rearranged gives 'tin'.
'la'+'tin'='LATIN'
