Jonah Hill got seriously choked up while making his second public apology for blurting out a homophobic slur at a photographer -- and called himself a role model ... for what NOT to do.
Hill was on "The Tonight Show" when he brought up the video we posted Tuesday -- Jonah yelling to the photog, "Suck my d***, you f*****."
Hill was emotional about using a word he calls "grotesque."
He also addressed the LGBTQ community directly, and begged young people to ignore the example he'd set -- "Don't respond with hatred or anger because you're just adding more ugliness to the world."
