PETA says baseball world should stop using "bullpen" in favor of animal-friendly "arm barn"

PETA is looking to "liberate the language we use in baseball." The animal rights organization wants the term "bull pen" be retired – and in its place, "arm barn" should be used.

In baseball, the "bullpen" is where pitchers warm up before taking the field. But PETA says there is another meaning. "'Bullpen' refers to the area of a 'bull's pen' where bulls are held before they are slaughtered—it's a word with speciesist roots & we can do better than that," PETA said on Twitter. 

"Switching to 'arm barn' would be a home run for baseball fans, players, and animals," the organization said. To really drive their campaign home, PETA changed its Twitter name to Arm Barn.
