Cowgirls (Dallas Cowboys nickname)

The Dallas Cowboys football team has many fans, but also many detractors. Some of these detractors (or fans critical of the team) use the feminine of cowboy—cowgirl. The team has been derided with the “Dallas Cowgirls” nickname since at least 1970.
 
The Dallas Cowboys Cheerleaders were first organized for the 1972-73 season. Although not called the “Dallas Cowgirls,” the Dallas Cowboys Cheerleaders have often unofficially been called this name (without the derogatory use as when applied to the football team).
 
 
Urban Dictionary
Dallas Cowgirls
Some dumbass nickname created by someone who thought they were the cleverest motherfucker alive. Probably spawned by a Washington Redskin fan, unknowing of how many less Super Bowl titles they have than the Cowboys.
Redskins Fan: I’ve got an idea! Let’s call them the Dallas Cowgirls! HAHA!
Cowboys Fan: Excuse me? I couldn’t hear you. I have 5 Lombardi trophies blocking my ears.

1970s
In the early 1970s, Cowboys manager Tex Schramm decided to change their image to boost attendance. At first he simply tried hiring professional models but that did not work due to the their lack of athletic ability. He then knew that he needed professional dancers with stamina who would be able to perform through an entire game. He worked with local choreographer Texie Waterman, who was charged with auditioning and training an entirely new and unique squad which would combine an attractive appearance, athletic ability, and talent as performers.

“We, the Buffalo Jills…have had it,” reads the challenge. “We are at the breaking point. No longer will we sit still for all those who rant and rave about the Dallas Cowgirls.

LOS ANGELES (AP)—Attractive women from Dallas and Denver have done a lot to bring cheerleading into focus, so to speak. But ine interested observer maintains the Dallas Cowgirls and the Denver Pony Express—prominent at the Super Bowl—are really no more than dancers.
