Naked Dingus
A guy peels off his pants, bends over, and whacks his butt with his fist like it’s a butt-shaped target. People do this to tease each other or to get a laugh from a group.
At the mall, my friend made me do the Naked Dingus in front of a crowd. I was so embarrassed I ran away.
During a video game tournament, my rival did the Naked Dingus to mess with me. I lost the game and my dignity.
My dad did the Naked Dingus in front of my mom. She laughed so hard she had to sit down.
