How to receive the Timmy helmet!

When I first saw the Timmy helmet while customizing my character in halo waypoint I was in love. I’ve heard people are starting to receive the helmet. Does anyone have a clue on how to get this helmet, and if you do please let me know.

There are a thousand threads about this topic right now and all you have to do is read a small bit to get the answer. You have to have played a certain amount of custom games.
