macrocranialism 

A non-scientific condition typified by the presence of a big (even gigantic) head. May also be accompanied by slight retardation or the presence of retard strength.

I feel so sorry for Mary, with John's advanced macrocranialism, their kids have ginormous heads. There must have been some stretching down in the vag from those big heads passing through.

microcranialism

A non-scientific condition in which a person has a head that is much to small for their body. This condition is often exacerbated by the individual's insistence on shaving their head. Also known informally as pin-head syndrome and cretinism. May be accompanied by slight retardation, or just a bad attitude.

That cretin down at the restaurant has a bad case of microcranialism, but I'd still nail his sister.
