It's when you see a group of girls or guys and they look hot, but when you see each person individually they are NOT, that an effect, when they are in groups they look hot.
I wish I was like those girls
What!, honey that the cheerleader effect, if you see them individually you will realize they are dorks and ugly bimbos.
Effect where when 3 or more women are located in a bar, pub etc scene together, they appear together as a good looking bunch, but when viewed individually, are actually unattractive. Thought to only be in effect with groups of women, but actually in effect with both sexes.
cheerleader effect where altogether the cheerleading team looks attractive but on closer inspection is quite ugly, the spice girls, the group of women who dance in a circle at the bar-usually with a pile of purses in the middle, occurs at any canadian fraternity common room where all together the men look hot but when checked out are actually bunk ass.
