Running away and building a fort in the bushes down by a bridge next to your local elementary school. Getting rid of all the spiders, etc and making some pretty cool stuff. The entire town is looking for you, but you were walking down to Albertsons-Dairy Queen-Back to your fort. You only got caught because your friends betrayed you.
Kris: "Well I built a fort in the bushes down by the bridge next to Gubser. Then I just got rid of all the spiders and stuff and made some pretty cool stuff.. I guess the entire town was looking for me, but I was walking back and forth a LOT between Albertsons-Dairy Queen to the fort.. Then my friends betrayed me Dx"
Reed: "That is like the DEFINITION of ninja Kris!"

A modification of the word "nigga". The term "ninja" is used in a context that promotes sociocultural correctness, yet still preserves that raw urban vernacular that we know and love. That being said, everyone can say it! Race is obsolete when it comes to the word ninja, my ninjas
what's good my ninja?
