Entry: anomic (adj.)
In context: "...Mildred had given him two days of high-volume shit for first sulking antisocially by the keg and then screwing out and abandoning her at seven months gone to a sandy room full of tanly anomic blondes who said catty things about her tattoos..."
Definition: Either from anomie (n.): Absence of accepted social standards or values; the state or condition of an individual or society lacking such standards.
anomia (n.): A form of aphasia characterized by inability to recall the names of objects.
While the former seems the best fit, I can definitely relate to meet anomic folks at parties in the second sense of the word.
