"I wrote this record about how your identity is really all you've got when you're in school ... so tonight, Jamey, I know you're up there looking at us, and you're not a victim," she said. "You're a lesson to all of us. I know it's a bit of a downer, but sometimes the right thing is more important than the music."

At one point in the song, she added, "Bullying is for losers."

Rodemeyer was found dead Sept. 17 outside his family's home in Buffalo, N.Y. He had posted several YouTube videos about his experiences as a bullying victim, mentioning his being a fan of Gaga in several of them.

His funeral, held Saturday morning at the St. Peter and Paul church in Williamsville, N.Y., was attended by hundreds of people, according to ABC News.

After news of his death was revealed, Gaga hit Twitter to express her emotions: “The past days I’ve spent reflecting, crying, and yelling. I have so much anger. It is hard to feel love when cruelty takes someones life.”

She added, “Bullying must become illegal. It is a hate crime.”

She added that she plans to meet with President Obama about the issue.

Meanwhile, the Amherst Police Department is looking into whether charges can be brought against the three teenagers who bullied Rodemeyer over the past year.
