This is probably best on an occasion like 4th of July or New Years, but would work for any occasion really. It could be a killer prank as well.

Step 1
Take the shake

Step 2
Shove the shake up your ass

Step 3
Lean over

Step 4
Fart

If executed correctly (And trust me, it may take some practice) the effect will be similar to a confetti popper. But it's weed, which makes it bad ass.
