Post-irony
Post-irony (from Latin post 'after' and Ancient Greek εἰρωνεία eirōneía 'dissimulation, feigned ignorance') is a term used to denote a state in which earnest and ironic intents become muddled. It may less commonly refer to its converse: a return from irony to earnestness, similar to new sincerity.
In literature, David Foster Wallace is often described as the founder of a "postironic" literature. His essays "E Unibus Pluram" and "Fictional Futures and the Conspicuously Young" describe and hope for a literature that goes beyond postmodern irony. Other authors often described as postironic are Dave Eggers, Tao Lin, and Alex Shakar.
