A phrase used when someone says that they will do something and chicken out at the last second

You probably wouldn't get it

'You wouldn't understand' refers to the meme: It's a _____ thing, you wouldn't understand.

It's a (insert anything you can think of: 'Person/First Name' 'Place/Jersey' 'Thing/Jeep') thing, you wouldn't understand. If you can think of it, it's been inserted into this meme.

The original phrase was "It's a black thing, you wouldn't understand". I could not find when it originated, but the earliest found it mentioned was in a book published in 1991 by Eugene Victor Wolfenstein, a social theorist and psychoanalyst, titled 'The Victims of Democracy: Malcolm X and the Black Revolution'.

when a challenging situation is presented, the phrase is used to provoke a person to attempt the challenge. Also used to taunt or encourage to fail.

Origin: Said when opposing team shoots a 3 point shot at high school basketball games.

An idiotic PSA comparing pirating a 1 GB movie file and stealing a full blown $50k+ 2 ton vehicle. The phrase was a part of an anti-piracy campaign called "Piracy, It's a Crime" created by Motion Picture Association. The PSA paints piracy as a bad thing even though it helps people living in 3rd world countries, aids developers test out software, and opens artists up to a whole new world of software.

"You wouldn't download a car" is a common variant of the phrase, originally created by Reddit user augreeko on /r/funny.

A term used by pirates as a joke, making fun of those old anti-piracy PSAs.

This expression is frequently used at public meetings taking place in localities across the whole of the UK. A meeting will be called to discuss such contentious issues as the removal of gypsy/travellers' sites or the influx of immigrant workers into a given community and, as tempers flare and fists shake, the shout will invariably go up: "You wouldn't get this in France!"

An allusion to France in the positive can be said to be unusual in Gall-hating Britain, but most Brits will concede a begruding respect for French militancy and people mobilisation during national debates - the roadblocks that kept petrol prices from going up being one example. Also, British people so applauded the outlawing of muslim headgear in French schools that the enmity of centuries could be felt to thaw almost over night. Therefore "You wouldn't get this in France" is an indirect form of the blanket, scapegoating racism I've become accustomed to in both countries.
