Gaggle of Nerds
A group of geeks who act like a gaggle of geese, loud, smelly, and always ready to yell at someone for getting the answer wrong or not knowing the difference between a proton and a pretzel.
They yelled at me for getting the math wrong in front of the entire class.
They showed up to the store like a gaggle of geese, all shouting about the new comic book.
They fought over the last piece of pizza like it was the final exam.
