“Giga Pudding” first emerged on the internet on October 27th, 2008, as YouTube user sukogi uploaded the dessert’s commercial.
The commercial itself is a stop motion animation of people reacting to the pudding, while a child is singing Sugoi Dekai (meaning so big) and “Giga Pudding”.
“Giga Pudding” was first defined on Urban Dictionary on January 20th, 2010.
The original YouTube upload dind’t gain a lot of traction up until October 2010, when it was uploaded to BoingBoing.
“Giga Pudding” became a veritable meme on November 30th, 2010, when 4chan moderator invisibro embedded the commercial on the /jp/ board.
The same day, moderators on the /b/ board implemented a word filter, changing all words to puddi, a phonetic transcription of the “Giga Pudding” song’s lyrics.
A video of the event was also uploaded to YouTube that day, by barricademadness, with the title 4chan – PuddiPuddi Day.
When users were inquiring about how to disable the filter, many resorted to the classic Delete System 32 prank.
