Texas students are planning to hang sex toys from their bags in protest at a law allowing people to carry concealed weapons on university campuses.
"You're carrying a gun to class? Yeah well I'm carrying a HUGE DILDO," Jessica Jin, organiser of
Campus (DILDO) Carry, wrote on Facebook.
About 3,000 people have signed up for the protest, which is planned for next year when the law takes effect.
Gun rights supporters have criticised the rally on the group's Facebook page.
Texas Governor Greg Abbott enacted the campus carry law in June. Under the law, university presidents are permitted to create so-called "gun-free zones".
"The State of Texas has decided that it is not at all obnoxious to allow deadly concealed weapons in classrooms, however it DOES have strict rules about free sexual expression, to protect your innocence," wrote Ms Jin, a student at the University of Texas at Austin.
"You would receive a citation for taking a DILDO to class before you would get in trouble for taking a gun to class. Heaven forbid the penis," she added.
