According to Knowyourmeme:
"Is a set of Facebook stickers featuring a large-eyed
purple pigeon in various situations, the most notable of which is an animated
sprite of the bird vigorously thrashing its head up and down. Shortly after its debut on Facebook in January
2016, the
purple dove sticker set quickly became a viral subject of photoshopped parodies and image macros on the social media.
It was created by Florida artist and Adobe creative resident Syd Weller’s “Trash Doves” sticker set officially made its Facebook debut and then added on January 31st, 2017, which included an animated emoji of a headbanging pigeon." As early as on February 7th, the sticker suddenly went viral in Thailand as a joke someone morphed it into another image making it look
like a purple dick flopping around. Eventually
4chan got a hold of it and decided to turn it into an alt-right symbol. The prank was a success, media outlets referred to it as a racist symbol and
people with alt-right leanings adopted it as using it as a symbol for "purple crayon" or referring to anything sexual or sexual violence perpetrated by an african american male because it looks so much
like a BBC flopping around and the fact it was used in thailand in a similar manner (animals with paws). Later on, info about the
4Chan prank caught on and now everyone uses it (not just alt-right
people) to describe anything perverse or drunken stupidity, as in "trashed dove" .
I read that article about that
rape that happened last week that you posted on facebook, what is up with all the Alt-right posts in the comments section?
What do you
mean?
There was all these trash
dove stickers being posted all over as a response!
