Why yes, yes I did.

Gotta look for me this time.

Some hints:
1. There are no vowels in my new username.
2. It's named after a sound Boo makes (might want to check my FA account for a hint)
3. It's eight letters long, and it consists of a four letter word typed twice.
4. The first letter is S, the last letter is F

If you check my FA you should see a hint.
