A guy pulls out his junk like it's a surprise and slaps it on a girl's face like it's a prank. It makes a *F'donk* sound so loud it could be heard in space.
My dad did this to my mom. She yelled and threw a shoe at him.
My cousin did this to his crush. She cried and hid under the bed.
A guy at the beach did this to a girl. She ran out screaming.
