'confused' is the definition.
(I've seen this before)

'deer mostly ran very slowly around lake' is the wordplay.
'deer mostly' becomes 'bamb' (I am not sure about this - if you are sure you should believe this answer much more).
'ran very slowly' becomes 'oozed' (to ooze is to slowly run out).
'around' is an insertion indicator.
'lake' becomes 'L' (geographical abbreviation).
'oozed' placed around 'l' is 'oozled'.
'bamb'+'oozled'='BAMBOOZLED'

Can you help me to learn more?
