The act, intention, or measure of how much one looks like John Malkovich. Often used by hipsters to adopt attitude and finesse.

Often alluded to because of John Malkovich's utter inability to not BE John Malkovich for even a second.
"Although far more subdued and tasteful that emo kids, indie nerds still clothe themselves in thrift-shop vestments, dishevel their hair, and slap on an annoyingly knowing smirk for maximum Malkmosity." - Something Awful
