Ah, that's a good catch. I'd have trouble providing a precise definition for a lot of these, but I know them. ("servo" is some type of engine; "degauss" is a button I pressed on CRTs to make them go "boing"; a "doula" helps with birthing somehow in a non-medical capacity.)
A servo is the movey bits that move the movey bits on the killbots.
Pretty sure a servo is where you get petrol and a sausage roll.
Most of the words I "know" from the female list are ones I've encountered in articles or novels that I didn't need to look up to get the gist of what I was reading. Same for a few on the male list, I've never needed to do anything with a thermistor or servo so I can only assume I recognise those words from SF.
oh that's interesting — I assumed the bar was being able to loosely define the words.
