'Honey Boo Boo' Mom Mama June Wedding -- The Pig Who Stole the Show

Just how redneckish was the Mama June wedding hootenanny?? TMZ has learned the "Honey Boo Boo" stars didn't just serve up a whole roasted pig (with the head intact) ... they also gave away HUNTING KNIVES to the male guests!

And it only got more gluttonous from there!

Our well-placed wedding spies tell us ... when June Shannon and Sugar Bear unofficially tied the knot, guests feasted on pulled pork sandwiches and ribs (ya know, from the dead pig), corn on the cob, macaroni and cheese, baked beans, rolls and sweet tea ... basically your cardiologist's worst nightmare.

And don't forget dessert ... which included a frickin' gourmet candy bar -- i.e. a bar full of candy -- which offered Airheads, Sour Patch Kids, Twizzlers, Swedish Fish ... you get the idea.

As for the gift bags -- women got red candles ... the men got small hunting knives ... and EVERYONE got diabetes!!!
