Gruesome Twosome

This is Phantom Couples Twosome in a 2x8, resulting in a virtual setup which is parallel waves. The point of this concept, aside from the funny name, is that the starting setup is always taken to be a 2x8, instead of the 4x4 that concepts like "Phantom Couples Twosome" normally indicate. That is, from normal parallel 2-faced lines, Phantom Couples Twosome places the phantoms to make a 4x4, so the virtual setup is columns. Gruesome Twosome places the phantoms to make a 2x8, so the virtual setup is parallel waves.

"Gruesome" is also used with other couples/tandem concepts, as in "Gruesome as Couples" or "Gruesome Tandem Twosome". In general, it directs that the phantoms be placed to make a 2x8, and that people be associated in pairs parallel to the long axis, creating a virtual 2x4.
