Naked Dingus
When a guy takes off his pants, crouches, and slams his fist into his butt like it’s a butt-shaped bag. People do this to tease each other or to get a laugh from a group.
At school, my teacher made me do the Naked Dingus in front of my class. I was so red I looked like a lobster.
During a birthday party, my friend did the Naked Dingus to get a laugh. I joined in and we both got in trouble.
During a video call, my cousin did the Naked Dingus and my whole family started laughing.
