In "Grease", what is the name of the main group of guys?

In the film Grease, the main group of guys is called the T-Birds. They are Danny Zuko’s greaser gang at Rydell High School and serve as the male counterpart to the Pink Ladies.

The T-Birds are associated with black leather jackets, slicked-back hair, cars and a rebellious 1950s image. The group includes Danny, Kenickie, Doody, Sonny and Putzie. Danny is generally treated as the group’s leader, while Kenickie is his closest friend and the owner of the car later known as Greased Lightning.

The gang appears throughout the film, including “Summer Nights,” “Greased Lightnin’” and the school’s final celebrations. Their rivalry with Leo Balmudo’s Scorpions helps drive the film’s car-racing storyline.

A frequent source of confusion is the original stage musical: the boys’ group was called the Burger Palace Boys there, while the 1978 movie uses T-Birds. Since this question refers to the film version, The T-Birds is the canonical answer.
