That's a common usage of the prefix 'anti-', however. You see it in things like antihero (still a hero), antiparticle (still particle), &c., where it means 'opposite, contrasting with the norm'.

Or antithesis (still a thesis).

Anti just means "against". The opponent could also fit the suffix (antithesis) or not (antisocial).

Contrast with "non" or "a" or "un'.

How about "cacopattern"? https://en.wiktionary.org/wiki/Category:English_words_prefix...

I guess it came from the tendency to call a technique that is frequently useful a 'pattern'.

Oddly enough the DRY principle seems to discourage patterns, but in the end it seems that it's a matter of moderation.
