If you mess with Kevin Smith's daughter, you mess with him.

One internet troll learned this after getting blasted by Smith for attacking his daughter, Harley Quinn Smith, on social media.

The negativity from the troll came when Harley posted a photo of herself to which the negative commenter wrote, “You’re ugly as sh*t. And that steaming horse shit of a movie, yoga hosers, should be banned. F**k your talentless c**t of a father for trying to compare it with the matrix. You’re cancer and I sincerely hope you end up like Lindsay Lohan and dead.”

Her protective papa wasn't having it and took to Instagram with a message of his own, putting the troll in his place.

In a lengthy post, Smith said that his daughter actually found the comment assuming and said, "I'd be mad if I had a tiny d**k and anonymous voice too."

The filmmaker though had a different take and called out the troll for picking on his teenage daughter.

"I have zero clue what the reference to#TheMatrix is all about but, wow - way to unload on a teen girl because YOU have nothing to do in life," Smith wrote, adding, "Attacking teen girls on the Internet is the saddest form of masturbation that exists and requires no discernible skill or talent. You want attention? Don't make yourself mad, make something original and fun. Because if you're not being useful in this world you're being useless."

Smith was met with tons of positive comments for shutting the troll down.

Harley also had a response for the creep writing in part, “At first I was like alright that hurts, but then I realized who the actual fuck cares??? Why should I let this sad ass troll who clearly either has a stick so far up his ass it’s affecting his moral compass or is compensating for an insanely small dick ruin my day??”

There hasn't been any new comment since from the troll so perhaps he went back to hiding under his bridge.
