Packing Beef
When a woman is getting her ass pounded by a bunch of guys at the same time. Usually five or more, and it's not a little bit of fun, it's a full-blown party in her butt.
My friend said her sister was in a packing beef session with six guys and didn't come out for three hours.
He told me his coworker got into a packing beef and now he can't stop talking about it.
At the club, I saw a girl getting packing beef and it looked like she was in heaven.
