Christmas is around the corner and it's time to figure out who's been naughtiest this year.

The Felt app, an app which allows you to send handwritten cards, is making it super easy for you to add people on to a naughty list and possibly send them lumps a coal for the holidays.

Why count on Santa to make sure they're on the naughty list when you can do it yourself?

People have added anyone from public figures to the common people in their lives onto Felt's own naughty list. So far, Donald Trump is in the lead with the most votes, with Harvey Weinstein and Vladimir Putin right behind.

You can make sure one person, like Donald Trump, wins the "Naughtiest Person Lump of Coal Gift" by casting a vote, or adding the names of people you personally know, and sharing the link on social media to increase your chances at winning.

You have until Dec. 18 to cast your vote on who's been worst behaved in 2017. On Christmas week, a single winner will receive one lump of coal for each vote casted, thanks to your help.

We all know someone who hasn't been on their best behavior so why not take this opportunity to express exactly how you feel? After all, the holidays are perfect for surprises.
