1. A staple image from 80's action flicks, the whole idea of something being cool for coolness sake despite lack of practicality. Given that ninjas are supposed to be stealthy and quiet, it is impractical for them to be riding these noisemakers. Usually, these ninjas also usually carry uzis and has the ability to climb up the side of semi-trucks.

2. Something that is doubly cool. Ninjas are cool. Motorcycles are cool. Ninjas on Motorcycles? Doubly cool.
1. This Michael Bay movie is like watching ninjas on motorcycles!

2. Samuel L. Jackson isn't just cool, he is like ninjas on motorcycles cool!
