a one-way bouncer made of bars, herding bodies forward and never letting them backtrack.
means A turnstile or revolving barrier gate that lets people pass through one at a time, usually in a single direction.
from A transparent compound of "turn" and "gate" — both solidly Old English ("turnian," to rotate, itself borrowed from Latin "tornare," to turn on a lathe; and "geat," an opening or door). The word simply names what the thing does: a gate that turns. It's a close cousin of "turnstile," where "stile" originally meant a set of steps for climbing a fence — both words for the clever little barriers that admit bodies one by one.
