Why does Ivan moody have a teardrop tattoo on his face?

I have no idea. The teardrop tattoo means you killed someone. He hasn't been in jail, and if he had killed someone, I'm sure we would have heard about it. One thing I noticed is from people I've seen who have it, it's on THEIR right side. (Lil Wayne, Ronnie Radke, etc.) and his is on HIS right. Maybe this means he lost a friend to suicide..? I don't know. Just an idea. Hope I helped a little :P
