I remember the time when I was younger and was first told that the collective noun for fish is called a 'school'. That is both weird and extremely imaginative, and made me wonder how people came up with these names. Well, we have another 25 names for animal collective groups that we bet will probably even change the way you look at them. So, the next time you see a bunch of owls chilling together, you'll know how to address the situation. We look out for you guys.
