When a person gets you to go on a date with them unknowingly. The person invites you to a group social event, but then is magically the only other person to show up to the outing and proceeds to treat you like a date.
Damn, I was forced into a ninja date! Josh asked me to go to the movies with him and some friends from high school, but then he told me in the car that nobody else was coming! He refused to let me buy my ticket and kept trying to put his arm around me the whole night!
