'moving clumsily' is the definition.
I know nothing about this answer so I can't judge whether this works.

'thus entering wood picaroon' is the wordplay.
'thus' becomes 'so' (synonyms).
'entering' means one lot of letters goes inside another.
'wood' becomes 'lumber' (I've seen this before).
'picaroon' becomes 'me' (where the crossword setter is 'Picaroon').
'lumber'+'me'='lumberme'
'so' put inside 'lumberme' is 'LUMBERSOME'.
