Goodish song by infinitely cool band - Pearl Jam
They're playing Nothingman on the radio.
Term inspired by the Pearl Jam song "Nothingman". Refers to someone who is visibly depressed but when questioned as to what's wrong responds with "Nothing, man."
Dude: What's wrong with Steve?
Other Dude: Dunno, he's being a Nothingman. Maybe we should give him some space.
Dude: Yo, Steve, what's wrong, man?
Steve: Nothing, man..
