I created a theory called "Whaletivity" basically for any group of decently looking girls or just girls walking around in general there is always a fat/ugly one with them or near them.
Go to the mall or look in your school's hallways and prove me wrong.

Friend 2: wait here comes the fat one to come and ruin it.
Friend 1: Whaletivity....
Sharon: Hey! Did you buy the jar of nutella I told you to pick up?
