Ghost skin

In white supremacist circles, a ghost skin (short for 'ghost skinhead') is a white supremacist who refrains from openly displaying their racist beliefs for the purpose of blending into wider society and surreptitiously furthering their agenda. The term has been used in particular to refer to the entryism of racist activists in law enforcement.

The term "hiding your power levels", originating from the anime Dragon Ball Z, is alternatively used by the online alt-right to reflect a similar concept.

History of the term
In an FBI Intelligence Assessment from 2006, the FBI Counterterrorism Division provided an overview of white supremacist infiltration of law enforcement and mentions that use of the term came to the agency's attention in late 2004. In 2001, two law enforcement officers in Williamson County, Texas, were fired after it was discovered that they were members of the Ku Klux Klan.
