Honey Boo Boo should stay the hell away from "Dancing with the Stars" ... even if producers lowered the age to make her eligible to compete ... this according to "Dancing" pro Karina Smirnoff.
Smirnoff was leaving the Dream hotel in NYC last night -- the same place where Lindsay Lohan was arrested back in Sept. -- when we asked her if "Dancing" would be better with a little Boo Boo in the ballroom.
But Karina wasn't laughing ... telling us, "I don't think that should happen."
As for Mama June -- Smirnoff doesn't think she should get a shot on the show either ... saying, "No ... I think we're pretty good with the people we have on the show."
