A Potsticker
A potsticker is when someone picks their nose and then uses their boogers to finger a girl. It's like a nose attack.
He picked his nose and then used his fingers to finger her. It was like a nose and a finger had a baby.
He picked his nose and then said, 'I'm giving you a nose massage.'
He had a booger on his finger and used it to finger her. It was like a booger was making out with her.
