Go look at your butt. At the top of the crack, look for scar tissue. You may have had a human tail. Sometimes babies are born with soft tails (though often up to 5 vertebrae are actually in it) which are just sacks of blood and tissue coming off of the butt. These are usually removed immediately by the doctors as it is painless and easy to do.
The longest human tail is this dude right here from West Bengel.
You now know what a true dickbutt looks like.
