Macca Slapper
A Macca Slapper is when you bounce your junk up and down like a meaty drum. It’s loud, it’s messy, and it’s only for men who don’t care if they smell like a sweaty gym sock.
My uncle did the Macca Slapper in the middle of church. The priest said prayers for him.
I tried to do the Macca Slapper in my pants. My mom heard it and yelled at me.
My dad does the Macca Slapper every morning. It’s his way of saying good morning to the toilet.
