Macca Slapper
A Macca Slapper is when you slap your junk so fast it looks like it’s doing the cha-cha. Only men can do it, and only men who are brave enough to admit they’re loud.
My dad did the Macca Slapper in the supermarket. The grocery store manager gave him a warning.
I did the Macca Slapper in my bedroom. My little brother ran out screaming.
My friend does the Macca Slapper during math class. The teacher gave him a pop quiz.
