The label "paraphilia NOS" is used to refer to an existing paraphilia that does not precisely meet the diagnostic criteria outlined in the DSM-5.
Paraphilias are sexual disorders in which individuals only become aroused by inappropriate objects or fantasies. In his 2008 book on sexual pathologies, Anil Aggrawal compiled a list of 547 terms describing paraphilic sexual interests. He cautioned, however, that "not all these paraphilias have necessarily been seen in clinical setups." This is probably because some of them are so rare, seemingly innocuous, or so interlapped with other paraphilias that they have never been heavily studied or documented.
