On Thursday night, a former student who was in the stands got video of North High School students chanting "powder blue, (gay slur that begins with F)" during the pregame.
South High School football players wear light blue uniforms.
"I was disgusted and I couldn't believe students were yelling that," said Heather Ike, who graduated from North High School in 1999.
She posted the video on YouTube and it has generated a lot of reaction.
"It is completely unacceptable and we will look at the video and see if we can identify students and they could be suspended," says Willoughby-Eastlake Superintendent Keith Miller.
He says that the principal at North High School did hear the chanting and intervened but that is not on the tape.
Students told Channel 3 News today that these types of chants have been going on for years, and that South High School uses it's own anti-gay slurs against North.
"This is not okay and we will address it, " said Miller.
With recent teen suicides locally and nationally, the Lesbian Gay Bisexual Transgender Community Center of Greater Cleveland says this is one more example of how words can hurt.
"We have reached a tipping point and this language has to be unacceptable to everyone," says Jan Cline, the center's executive director.
