the bouncer that thinks you're a robot until you find every traffic light
means A test on a website designed to tell humans apart from automated bots, usually by asking you to read distorted text or identify objects in images.
from An acronym, born in the early 2000s, for 'Completely Automated Public Turing test to tell Computers and Humans Apart' — a nod to Alan Turing, the mathematician who first imagined a test for machine intelligence. The spelling was deliberately bent toward 'capture,' since the whole point is to catch you proving you're real.
