meatbrain

An unintelligent person.

'Plague take the fists of lust-ridden sailors,' snapped the herbalist in riled temper. Planks scraped as she jammed her door open wider to admit the next client on her threshold. 'If you've brought me the meatbrains who savaged that girl, let me tell you, I'm likely to geld him.'

They snorted and shook their heads like I was a meatbrain.

A biological brain (as opposed to an artificial or man-made one).

Installed on meatbrains whose habituation to computer-mediated activities has made them perilously vulnerable to infection by aggressive memes, the 'Babel' virus corrupts and overwrites the deep structures of human language, thereby 'crashing' the mind, and civilization with it.

The fact that programming languages often resemble English words like body or if is a convenient accommodation for our puny human meatbrains, which are much better at remembering commands that look like words we already know.
