Honey Boo Boo's Mama -- 'South Park' Spoof WASN'T FUNNY

Mama June wasn't laughing at the way she and her family were portrayed on "South Park" earlier this month ... telling TMZ the way the show focused on her weight was just plain "trashy."

June and her daughter Alana -- aka Honey Boo Boo -- just appeared on "TMZ Live" ... when we asked how they handled being spoofed on shows like "South Park" and "Saturday Night Live."

June's response -- "Me being a big person, I didn't take offense ... that show is just not a show that I would want to be on in the first place."

She added, "Just the way they portrayed the show ... it was kinda trashy."

June, Alana and the rest of the gang were mocked hard in the "South Park" ep -- in which Honey Boo Boo got a heart transplant ... with a pig heart ... after eating too much 'sketti and butter."
