I voted stickers

The "I voted" stickers are the little stickers that they give you after you vote.

I wore mine on my backpack earlier today.

"I voted" sticker

Something an egotistical person wears to show they did something "great".

Voter: *Wears a "I voted" sticker*

Voter: *inside their own head* Yeah! I'm the best person in the world because I voted!
