look up any word, like blumpkin:
A boy who is, metaphorically, full of knowledge and wisdom like a tree.
'You're not a tree of knowledge'
'Yes I am. You're just jealous because your a mushroom of stupidity'
'Stop extending on Daniel's ladder of knowledge'
'I think you'd better watch out little mushroom, the lawnmower is coming.'
