Labia that takes up too much real estate in the cooter district. Often looking like the woman is trying to smuggle a piece of beef jerky in her panties.
"Damn! Look at the dangle beef on her!" "Eww, I know! She's got so much scrap meat down there that Oscar Mayer wants to shoot her snatch for some bologna commercials."
A grudge or grievence against a person or persons generated within a mosh pit.
Pit Beef is created mostly during hardcore/punk and/or metal shows, where moshing and dancing turns more into an angst driven argument or fight. Much like when dogs play with eachother and it appears as if they are fighting, so is the Mosh Pit. Encompassed within The Pit, sometimes moshing and dancing can generate Pit Beef with others, causing problems and kids "starting" with eachother.

I thought I had Pit Beef with that kid Potty, but then after the show he was buyin me beers.
