Exclusive VideoHoney Boo Boo absolutely inhaled a giant slice of watermelon, and taught a table full of kids a valuable lesson -- she will RUIN YOU in competitive eating!
It all went down in Panama City, FL -- where HBB and the fam are vacationing -- during a children's watermelon eating contest, and honestly ... Joey Chestnut himself would applaud the 8-year-old girl's performance.
It's clear from the video -- the 7 other kids never stood a chance. Just like that poor, poor melon.
Mama June taught her baby good ... never waste a single drop of food.
