dacklacker
A dacklacker is someone who won't stop licking the dack, even when it's covered in snot
He's a dacklacker. I saw him do it in the car. It was gross.
My teacher said, 'You're a dacklacker, and I don't want to see you again.'
He texted me: 'You're a dacklacker. I know you've done it in the hallway.'
