Agree with Steerpike, but ... Hyper- as a prefix means over, beyond, more than is normal. Cephalic means relating to the head. So 'hypercephalic' could mean 'having an unusually large head'. Perhaps it is a clever (or pretentious) way to call someone big-headed. :)

I agree as well - it's a made-up word, but you can deduce the meaning from its parts, as Claire has shown. It turns out it's straight from a cartoon called Sam & Max: "Aw, it's a cute little hypercephalic kitten." http://saboo.deviantart.com/art/Max-9675478 http://en.wikiquote.org/wiki/Sam_%26_Max It's also probably a mispronunciation of "hydrocephalic", which means an excess of fluid (and therefore pressure) around the brain, leading to a swollen head, physical problems from a malfunctioning brain, and possible death. This sounds like typical Sam & Max humour.

That would suggest it is not a real word.

I was going to attempt to answer this, but it looks like everyone else got there first!! Beth, that sounds horrible!! :(

Sorry for your loss,Beth! 我不知道腦積水會那麼嚴重.
