Three Ninjas 

1. A great movie to quote that was made in 1992 about three ninjas trained by their grandfather.

2. A nickname to a confused, but innocent girl, who didn't know her friends were quoting the movie, because they watched it without her.

"What movie are you quoting?" "Chelsi Marie! Three Ninjas!" "Nielson."
