"tall head" refers to a person who is overly stubborn and un-wavering in a descision,be it wrong or right they will not care because they have a "tall head" about the subject,and refuse to admit that they are wrong at all costs.
My friend was being very condescending to me in relation to how to correctly roll a cigggarette,however he was oblivious to his condescending nature,which brought about a cringe on the faces of everyone listening.He had a very "tall head".
