When the cover of a porn video is misleading or intentionally lies about what is actually in the video.
Mike: Dammit, I fell victim to another bate and switch last night.
Ike: What's that?
Mike: When the porn video doesn't match what is advertised on the cover. You know, like when the hot blonde with triple Es on the cover isn't in the movie.
When the movie advertises twins, but they appear in separate scenes. They say there is a Bukkake scene, but it is only a threesome. Promise double anal, but its only two guys taking turns. You think you're getting hot fresh teens but they have saggy boobs and c-section scars.
Ike: Yeah, dude, it is a cruel world out there.
