Your throat's bouncer, rejecting things before your brain even votes.
means An involuntary throat contraction triggered when something touches the back of your mouth or throat, designed to stop you from choking or swallowing something harmful.
from 'Gag' as a verb meaning 'to choke or retch' has been in English since the 1500s, likely imitative in origin — the word itself almost sounds like the convulsive sound it names. 'Reflex' arrives later, from Latin reflexus ('bent back'), borrowed into physiology in the 1800s to describe automatic, involuntary responses that happen before conscious thought gets involved. Pair them and you get a precise medical term for something far older than its name: a protective reaction humans share with many other animals, hardwired into the back of the throat long before anyone bothered to label it.
