About
I Came is an image macro series that typically takes screen grabs of moments where the subject is making a happy or orgasmic face, with a caption that reads “I came”. Alternative versions associate the text with water or other liquids, or large explosions and destructive events.
Origin
Encyclopedia Dramatica claims:
The meme comes from the final scene in the 1998 movie Happiness, written by Todd Solondz, where the 11 year old son of a serial child rapist masturbates to his first ejaculation, has the jizz licked up by his dog, then the dog runs up to the boy’s mother and licks her face. The boy comes in after the dog and simply says “I came”.
One of the first image macros may have originated on 4chan’s /b/ boards with this picture of Lazytown’s Stephanie:

“I came” is too broad of a search term on it’s own, but adding “meme” to the keywords shows a significant increase in search since May 2010.
