The idea of “puking rainbows” was first released about 6
years ago according to the website knowyourmem.com. The meme didn’t become
popular again until 2009 when the site RainbowPuke.com was revamped and people
started to submit photos of puking rainbows. It is still a highly used memes.
There is a Nyan Cat video where the cat is barfing a rainbow, a part in ASDF
Movie 2 (another viral video series), and recently done in the new Disney
channel cartoon, Gravity Falls, where a gnome is puking a rainbow. My guess for
why it took so long was because the site PukingRainbows.com was taken down for
several years. It seems when it launched in June 2009 everyone hopped on the
rainbow puking train. It is a pretty self-explanatory meme, its people, things,
and objects, puking rainbows. When looking at Google interests, searching for
puking rainbows reached its peak of 100 in both March and April 2012 and in
Spain and the U.S. It first started in about September 2006 and has been
fluctuating ever since. Recently it has been decreasing since April 2012. There
has been a lot of other memes and mediums that have used or connected to puking
rainbows (examples already given early). In all honesty I think it is
absolutely hilarious.
