To remove spoilers from a description, especially a movie or TV summary, that might otherwise give away the ending or a plot twist to the unsuspecting reader. Can either be done by omitting spoiler content entirely, or by masking it on a web page in a way that the user has to click through or highlight text to read it.
You should spoilerize that movie review better, so people don't find out he was dead all along.

In vehicles:

A device attatched to a car- usually at the rear, that changes the aerodynamic shape of a vehicle, reduces drag- which does not add downforce- and acts as a rear diffuser, eliminating a vacuum effect at the rear end of the car and improving gas milage.

Often mistaken for a wing or airfoil, which does the opposite by creating drag.

Before you hit that down button, google wing vs. spoiler.
Often mistaken as a type of airfoil or wing, spoilers do not increase down force of the rear wheels, but actually reduce it.
