The mississipi slinky slap is when you pull your moist dick out of another man and and he procedes to grasp it until it turns blue, then he will give it a nice slap with a 2 by 4. This will knock your balls into your own asshole. Illegal in all countries.
When tim pulled the mississipi slinky slap on me, i couldnt get my balls out of my ass for a week.
