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!
