Ninjavitus 

A rare disease that gives you the skills of a level 8 ninja master.

Ninjavitus symptoms may include friends and family dying from sudden and uncontrollable karate chops, and the urge to carry ninja stars.

YumeChan, this is my word, I made it up long, long ago and you have no right to use it. So for the time being, you are now my bitch. And if you don't like it, TF.

YumeChan is a big gay homo who slaps men's faces with his wiener

Ninjalicious

A descriptive word used to describe something that is both delicious and amazingly sexy like a ninja! Ninjalicious generally is used in the description of rad objects. I would not, for one, call one's little sister "ninjalicious," unless, of course, she can say 'popsicle' in Turkish while she kicks one's ass and looks awesome the entire time.

A. My new hairstyle is completely ninjalicious! Everyone thinks it's totally radical!
B. Your mom is ninjalicious. I'd know...I did her last night, and her moves were saWEET!
