Noted for his gangster portrayals throughout the years, anyone who knows anything about cinema will attest that an amped-up Robert De Niro is something to be feared. In the latest Jimmy Kimmel Live “Mean Tweets” segment, Bobby D meets his Twitter haters head-on and he’s in no mood to take any shit.

“Who are you? Who does this? Are you some little 15-year-old with nothing better to do in your life?” retorts the actor when user @PoliticallyILL1 questions his famous mole. From there, the comebacks only get wilder, with De Niro proving he still has plenty of fire left in the belly.

Watch the hilarious footage above, and then find out why we’re so excited about Scorsese and Bobby reuniting for The Irishman.
