This story is a great example of why Riot is an amazing company towards it's fanbase.

My GF is a huge huge fan of poros so for our 2 year anniversary I decided to buy her more of those soft poro plushies that you can buy from the LCS. Once I gave her the poros, she asked what a group of poros was called and I had no clue so I sent an email to Riot asking what it would be called since it was just one of those things that was never mentioned. Unfortunatley the Rioter (Dart) wasn't 100% sure of the answer himself so he forwarded the email to the lore department who started to search for answers! A week later, I got another email back saying they had found some old journal entries and wanted to send them to us! Today the package was delivered and this is what was inside! Journal entries + text are in this album along with 3 little poros they sent us! http://imgur.com/a/LLKGD#0 TL;DR: GF didn't know what a group of poros was called, emailed Riot and they went out of their way to get an answer for us. Oh, and a group of poros is called a fluft of poros.
