Puking Rainbows through Portal
Adam Rifkin stashed this in Rainbows!
BTW, I understand the appeal to 4chan about puking rainbows, but as an old schooler, I just wanted to note that the very first popular rainbow puke meme was in 1990 in Spike and Mike's Festival of Twisted Animation. One of the most popular was a short animation called "Technicolor Yawn" and was basically an animated figure puking rainbows.
It was so popular, they handed out barf bags for future shows in 1991-1995.
I love that 4chan's love of the technicolor yawn led to Reddit, then Tumblr, then Imgur and 9gag, spreading the meme.
Thanks for the origin story, Greg. A better origin story than Know Your Meme has, frankly.
