Chucklehead 

Apart from being used to describe a stupid and awkward person, the term "Chucklehead" may also be used as a term of endearment. Usually used for friends with poor communication skills, that arrive late to your social gatherings, that are ignorant and oblivious, that have trouble forming sentences with correct subject/verb agreement, and that are just plain stupid.

Bob just called,he's lost in your neighborhood and is going to be late...what.a.chucklehead
