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.
Me and Brophy have Pit Beef. Last show he windmilled right into my sister.
I thought I had Pit Beef with that kid Potty, but then after the show he was buyin me beers.
2. The Goddamn is a phrase that can replace any word(s) you don't feel like saying or can't think the name of. The Goddamn is most effective when delivered properly, often at the end of a sentence, confusing some while providing entertainment to yourself and others. When used properly, you will most likely get the response, "What the hell is the Goddamn?", or, "The Goddamn what?". If you are able to produce this result, give youself 2 points.
"Give me The Goddamn."
"Where the hell is Pete?"
"He's out talking on The Goddamn."
"Sorry I'm late, I had some trouble with The Goddamn."
