'Redneck Island' -- The Nipple Ring Beer Bong

EXCLUSIVE

A group of rednecks just took beer bonging to a whole new level ... by introducing a nipple ring into the mix -- and the results are extremely uncomfortable.

Lucas Albert -- a cast member on the upcoming season of CMT's "Redneck Island" -- caught the attention of another housemate for having a nipple ring ... and that's when things got weird.

Eventually they decide to pour liquid gold into a beer bong by attaching the can to his nipple ring ... and well, we've already explained too much.

So just watch ... and don't try this at home -- unless you're a redneck, obviously.
