An alien character (or an entire race) who is shown to enjoy specific things relating to human culture. A direct subtrope of Alien Arts Are Appreciated, when it's the aliens who like human culture. Perhaps it's a certain food, or a certain activity. When played straight, this can be used to allow an alien character and a human to bond, showing that they are Not So Different. Or this can be Played for Laughs, when an alien who has little grasp of human culture and social conventions suddenly shows himself very aware of a certain pop culture element, or addicted to some human activity the viewer would not think him capable of grasping.
