Going from anal sex to vaginal sex. Commonly attempted without consent in an underhanded, mischievous, or bastard like manner.

A pubic hair piece. A toupee for the pubic area/genitals. In the 1700’s when mercury was used to treat sexually transmitted diseases (Gonorrhea or Syphilis) one of the side effects was the loss of pubic hair. To disguise this condition, that was not cured by mercury, a Merkin was employed.

An experienced party technique which involves one or more party-goers drugging their friends whom explicitly requests to be drugged in such a manner, or, being accidentally being given a different drug than expected at a particular moment. This can work in many ways, such as by surprise--like dropping a small hit of something into a friends drink, or boofing a qualifying friend while they are sleeping. Accidentally giving a friend molly instead of cocaine is a common example of a Dirty Rogue. The more direct, "take this and don't ask questions," approach would also qualify. The user may or may not be made aware that they have been "given something", as this is the point of the Dirty Rogue. Safe drugs and dosages are always used during a Dirty Rogue.
