Actual British engineers.

[lloydwood]

The black-and-white war-film boffin put a comfy manageable face on military tech; like a lot of stereotypes he provided a sense of familiarity that let you stop asking anxious questions. I'd guess that the stereotype is still around, amazingly, when it's decades out of date, and actual British engineers are more likely to be smoking a spliff than a pipe, and wearing a black T-shirt that says Plus Plus Ungood on the front instead of a labcoat, and even from time to time be women, exactly because the post-war industrial tradition in this country crashed without leaving a culturally obvious successor.

It appears that plus plus ungood is now in use as an expression, but only after the introduction of ++ungood; in 2002.

If you don't know Orwell ("doubleplus") or programming ("increment") just say what you see. I've inadvertently managed to dumb Newspeak down even further.

Plus Plus Ungood? This is New New Speak.
