The boy band effect is the phenomenon when a group of 3 or more boys of mediocre looks are hanging out together in a bar, mall, sporting event etc. When alone the boys would not merit a second glance from a nearby female but when together their averageness combines to form a cute cluster of males like that of a boy band. Works best when one guy is actually good looking. The boy band effect pulls up the ranking of looks the same way a British accent, suit, instrument or baby/puppy would. See cheerleader effect for female equivalent.

Tory - "No, look closer"
Jessica - "You're right only one is cute - total boy band effect - bummer"
