The term “bullpen” has been used in baseball since the sport really took hold around the late 1800s.

In baseball, the bullpen refers to the area beyond the outfield wall where pitchers warm up. Starting pitchers can be seen warming up before games while relievers do their warmups during games as they get ready to substitute for whoever is on the mound.

Now, People for the Ethical Treatment of Animals (PETA) is hoping those around the sport will reconsider using the word “bullpen.” In a release Thursday, PETA said the baseball world should substitute the word “bullpen,” which references the area where bulls are kept for slaughter.

Their suggestion? Arm Barn.

“Words matter, and baseball ‘bullpens’ devalue talented players and mock the misery of sensitive animals,” PETA executive vice president Tracy Reiman said. “PETA encourages Major League Baseball coaches, announcers, players, and fans to changeup their language and embrace the ‘arm barn’ instead.”

Where the word “bullpen” comes from is up for debate. The Cincinnati Enquirer is thought to have been the first to use it in 1877 in O.P. Caylor’s game recap.

“The bull-pen at the Cincinnati grounds with its `three for a quarter crowd’ has lost its usefulness. The bleacher boards just north of the old pavilion now holds the cheap crowd, which comes in at the end of the first inning on a discount,” Naylor wrote.

The paper also noted the Durham Bulls tobacco ads would be plastered across stadium fences and the pitchers would warm up on the other side. Thus, bullpen. The term has also been synonymous with prisoner of war camps and stockades.
