Swinging beef
A bull's testicles which are removed, cooked and eaten.
Them boys cut off that old steer's ballies and ate swinging beef for a week.
Swing Beef
To be well-endowed; to have a horse cock, a massive pants python, a big ol' piece of meat dangling between your legs; to have a huge dick.
"Dude, Patrick Ewing sure does swing beef. Back when he played basketball, he had to duct-tape his schlong to his inner thigh so it wouldn't go flopping out the bottom of his shorts!"
