Bullpen in baseball is a term used to denote a area where the pitchers warm-up and do their stretching exercises before a game. Its location depends on the ballpark. Incidentally a group of players or relief pitchers to be exact are also collectively known as bull pen. The origin of this term is uncertain and vague. There are several theories on how this term came to be a part of baseball but none of them are proved beyond doubt.
One of these theories state that in the early days of baseball the player and the audience were ushered into the playground like cattle and hence the term bullpen came into being. There are several other theories like it symbolically represents a fenced area where the bulls were sent for slaughter and here they represent the relief pitchers while the ball park is their pen.
