(Noun) - the process of elaborate, underhanded, yet whimsical deceit of an unwitting stranger, usually emphasizing the use of telecommunication devices and web-based social networking forums and/or media platforms. The Sandy Effect cannot be borne through malicious intent, only through the serendipitous collision of an unsuspecting victim and an unsuspecting "Sandy."
Person 1: Did you hear about Stacey? She wasted the whole week texting some random guy who she thought was her TA.
Person 2: Oh snap, no way! Another victim of "The Sandy Effect"...

When you are up by 2 or more touchdowns going into the 2nd half of a game of NFL blitz and suddenly your opponent develops super human powers, making catches that are not humanly possible, and forcing fumbles like the football is covered in crisco.

Friend: Yea? what happened?
Me: Blitz effect dude, he beat me 51-50
Friend: oh, shitty

The effect that happens when the particularly obnoxious fanbase of a video game lowers your opinion of the game itself. It is important to remember that a horrible fanbase does not necessarily make a bad game.
"I don't know man, I'm seriously getting sick of hearing about Skyrim. Do I even want to bother with a game that only meme-spewing idiots seem to enjoy?"
"Don't bash the game itself until you play it- you're getting the FF7 effect, dude."

When you see a commercial so many times, you start to hate the product even if you used to be an avid fan before.

The effect that happens in a situation where an innocent bystander is accused and punished for committing an action or crime that they did not make because the real perpetrator is too famous or essential to be punished.
This is referenced by the infamous incident where an episode of Pokémon was aired in Japan and gave numerous kids seizures due to rapidly flashing lights, caused by an attack from Pikachu. Since Pikachu was and still is the poster boy for the Pokémon franchise, Porygon, the starring Pokémon of the episode, was blamed and punished instead despite not being responsible for it.

Person 1: Why am I being punished for something I didn't do? It was clearly Jimmy's fault!
Person 2: It's the Porygon Effect; Jimmy's too important to be punished.
