Weird user icon?

[Yell-O]

So, I just reinstalled Yosemite on my rMBP and when I got to the "create user" section of the setup, I got an icon that I've never seen before. When I click on the icon to change it, it's not in the list of default user icons. Has anyone else ever seen this?

That is in the default Yosemite list for me. I think you are fine.
