Move over Harlem Shake! There's a new craze that has hit YouTube. It's called gallon smashing it is probably exactly what you think it is.

Basically you grab a couple of gallons of something (milk, OJ..whatever!) and walk through the store. When you are ready you pretend to dramatically fall and smash the gallons so that the fluid is just everywhere. It makes a huge mess. Of course, the reactions of those who are around seeing this very dramatic display are just priceless.

So, next time you are at the grocery store and see someone carrying 2 gallons of something and nothing else. Be weary and move away. You might just be the next victim who goes home covered in milk.
