"erogenous zoning": sex-traterritorial jurisdiction (as in "Sex-Traterritorial Jurisdiction and the Exercise of Federal International Police Power after United States v. Clark, 435 F.3d 1100 (9th Cir. 2006)").

"Erogenous zoning," by the way, seems to be credited to Larry Tribe; it's used in the 1988 edition of his treatise.
