When someone reveals a previously unknown aspect of something which you likely would have rather learned on your own.

*discussions of art media such as video games, movies, etc. especially vulnerable.

When you find out something about a movie, TV show, book, or video game that you wanted to find out on your own.

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.

Something that could ruin something aobut a game for someone who hasn't played it yet. For example, revealing major parts of the plot or big storyline events to others.

Meaning One:

An aerodymanical feature that 'spoils' the air flow by forcing any air that reaches it into the shape, pushing the rear end of the vehicle downwards, this is used to improve handling and to increase downforce.

Meaning Two:

Information that could spoil the experience of a certain game, may that be a console game or a PC game. Spoilers usually come woth warnings to stop people who havent seen the whole game yet, to prevent them seeing the information before they discover it themselfs.
Meaning One:

Holy hell when i got up to 100 MPH my Evo started to get some upforce, i need to get myself a spoiler!

Meaning Two:

Dahm, on the Atari forums someone revealed a spoiler and I havent started the game yet!

Something a ricer attaches to the back of his car to get downforce on the rear wheels. Too bad their rice rockets are front wheel drive!
Look at that totally homo 747 wing! I didn't know it was from Spyder Sebring WRX Hyundai Honda Techno Dream Team Racing Works! They should bring in some rudders maybe the thermal tiles from Columbia so they can protect their car from burning up when they drive 30 mph on the freeway!

Internet slang: A unknown fact within a series (generally of a future event) that ruins the tension and mystery for newer fans.

What constitutes a spoiler is often debatable but a good rule for determining one is the "3 of 6 rule". The "six" are Who, What, Where, When, Why, and How. If a comment has atleast three of these six then it can generally be called a spoiler.
One of the only exceptions to the "3 of 6 rule" is "X dies" or "X is dead" as this is still considered a spoiler because the When or How is generally considered irrelevent when it comes to deaths.
"Vader, Luke" >This statement is WHO+WHO and thus doesnt convey a spoiler as no information is being revieled.

"Vader is Luke's Father" >This is WHO+WHO+WHAT, and thus fits the "3 of 6 rule" and is a spoiler.
