Lively trip with side getting sozzled (8)
I believe the answer is:
spirited
'lively' is the definition.
('spirited' can be similar in meaning to 'lively')
'trip with side getting sozzled' is the wordplay.
'with' says to put letters next to each other.
'getting sozzled' is an anagram indicator (sozzled can mean drunk and therefore disordered).
'trip'+'side'='tripside'
'tripside' anagrammed gives 'SPIRITED'.
(Other definitions for spirited that I've seen before include "Sparkling" , "Energetic, animated" , "Vivacious" , "Mettlesome" , "Vigorous" .)
