Bleeding like a stuck pig 

Way back when, piggies would be stuck with a slaughtering knife in order to bleed out well, hence the expression, "Bleeding like a stuck pig."

"Cheese and rice! Jimmy got hit hard with that baseball! He was bleeding like a stuck pig!"

Bleeding like a stuck pig 

To bleed an extreme amount of blood. The expression likely comes from the method that farmers would slaughter their pigs. Pigs, when injured, release a bodily chemical that ends up making their meat taste bad. Because of that, farmers would stab the pig with a knife, specifically in an area that draws a lot of blood (such as the jugulars).

Did you see that dude get shot? He was bleeding like a stuck pig!
