Tina Fey revealed the back story of the line "You go, Glen Coco!" from the original 2004 teen comedy film "Mean Girls."

Last December, Tina and the cast of the new "Mean Girls" movie paid homage to the original stars of the hit film and talked about all things "Mean Girls" in their interview with Fandango.

When asked about their favorite line from the original film, the actress-playwright said, "I think I will also say, 'You go, Glen Coco!'"

Tina continued, "Because it's just my brother's friend's name... When I was writing the movie, I was just using random names."

"Now, I've ruined his life," she quipped before adding, "Thanks again, Glenn, for not being mad about it."

"Sometimes, I'll be in Target, and I'll be like, 'Oh, there are shirts with Glen's name on it.' Oh, sorry, Glenn," she continued, drawing laughter from her film's stars.

 

Meanwhile, the real-life Glenn Cocco told Yahoo Entertainment, "I get a laugh sometimes when I purchase something using my credit card."

Cocco has been friends with Tina's brother for a long time as they grew up together in the same neighborhood outside Philadelphia. They also attended the same schools in high school and college.

Like the "Mean Girls" creator, he works in the movie industry but as a film editor.

While there were jokes about his name because of the movie, he said he was not mad at all because they weren't doing him any harm.

"It's funny to me that Tina thinks she ruined my life," he said.

 

The iconic line "You go, Glen Coco!" was used by Damian Leigh (Daniel Franzese) as he gave out candy cane grams while dressed as Santa in the film.

One of the recipients was a brunette student in a blue hoodie named Glen Coco, portrayed by background actor David Reale.

"Four for you, Glen Coco! You go, Glen Coco!" Damian's character told the boy while throwing him the candy.

Meanwhile, Reale told Dazed in 2014 that he wasn't officially cast in the film. While he auditioned for a different part in the movie, he didn't get in.

When the production ended up filming in the park near his Toronto apartment, he wandered to the filming site to see if he could watch some scenes and maybe get a free lunch.

"I sort of hung around with the background performers and ended up getting lunch because everybody just assumed I was actually hired to be there," he said.

After the director recognized him from his failed audition, he gave him a scene as a consolation. The background character Glen Coco was given to him.
