And they only need to be one word.
They could reflect something about you (where you live, your favorite song, etc), your "real" avatar (not the MASQ one), etc.
Again - it only has to be one word.
But if it's a favorite song (a song called "The Devil Beside You") or something that has more than one word - please provide the entire clue. (So for example, if the song is "The Devil beside You", do not just say "Devil", "The", or any variation of that). Just the entire thing.
It should be obscure enough where it doesn't immediately give it away (like I wouldn't put "Tawmis" as my one word clue)
