A scene in The Social Network Mark wants the mailing list of Phoenix Club members from Eduardo. The conversation was :
Mark Zuckerberg: These guys know people. And I need their emails.
Eduardo Saverin: Sure.
Mark Zuckerberg: Good. Give me the mailing list.
Eduardo Saverin: Jabberwock12.listservharvard@edu.
Mark Zuckerberg: These guys! They're literary geniuses cause the world's most obvious Lewis Carroll reference is in there.
Eduardo Saverin: They're not so bad.
Mark Zuckerberg: I'm just saying.
So what's the Lewis Caroll reference?
EDIT
Ok so it was a poem of Lewis Caroll named "Jabberwocky". Jabberwocky is a nonsense poem written by Lewis Carroll (from the answers see below). But why Mark is mocking them by saying "literary geniuses"?
