Top Definition
the passive process by which one learns of something via a. social networks or b. other forms of internet-based informational services. It is key to note that the knowledge in question must be about something one does not have first-hand exposure to and/or experience with.

Used most specifically in reference to second-hand knowledge of internet-based phenomena/culture such as a meme.

Etymology: An adaptation of osmosis as defined as a study method.
"The cake is a lie?" Yeah, I know what that references - I've never played Portal but I learned about that meme through internet osmosis.
