Lung Ninja

A stoner game in which you have 12 throwing knives, 4 throwing stars, and 1 tomahawk. What you do is take a big hit off a pipe, and hold it in, throw all of the items listed above before you exhale. If you do exhale before all the items are thrown, you cant throw any more. You add all of the points and thats what you receive. The goal is to throw all the items and get the highest score while you get the highest.

I played lung ninja yesterday and won. I also had a bad case of the munchies.

sticky ninja

An act whereby an individual utilizes stealth and cunning to steal a passerby's towel while in a shower. The next step involves masturbating to completion into the stolen towel and placing it back, undetected, from whence it came. The victim will find themself unknowingly massaging their body with semen.

Dude, I totally just gave Bucket the Sticky Ninja.

I smell oddly fishy and salty. I think someone may have given me the Sticky Ninja.
