"The Backbone Zone" is "an innovative approach to bystander intervention" that encourages students to stand up against sexist and homophobic slurs.

A funny thing to do would be to replace the picture of the cat with a picture of a vagina and then say, "Now that's worth fighting over!" When your nearby classmate, acting "mature," shakes his head and tries to walk away from you, you catch him with the left uppercut to his chin right under his outstretched hand of peace.

Later, it turns out that that classmate was actually a bully.
