'feller with glasses at washington right?' is the definition.
I can't tell whether this defines the answer.

'with glasses at washington right?' is the wordplay.
'with' becomes 'w' (abbreviation).
'glasses' becomes 'OO' (OO looks like spectacles).
'at' says to put letters next to each other.
'washington' becomes 'dc' (Washington DC).
'right?' becomes 'utter' (I can't explain this - if you can you should give a lot more credence to this answer).
'w'+'oo'+'dc'+'utter'='WOODCUTTER'
