Added a new phrase to my lexicon

“drive-by” UI

A class of user interfaces written by developers who look down on frontend developers because “UI is easy”. These developers build spectacularly brittle UIs in a short amount of time, then move on to whatever other activity they deem worthy of their skills, leaving chaos and destruction in their wake.

These hastily-built UIs underperform and blow up regularly, after which they usually become the responsibility of actual frontend developers to extend.
