Camila Morrone flexes her knowledge of Toronto slang on Jimmy Fallon

American-Argentine screen star and model Camila Morrone showed off her impressive knowledge of Toronto slang this week on an episode of The Tonight Show Starring Jimmy Fallon.

Morrone appeared on the show plugging her new psychological horror miniseries, Something Very Bad Is Going to Happen, premiering this week on Netflix. 

While shooting the series, Morrone picked up some Toronto knowledge — including local slang — from her Canadian co-star, Adam DiMarco.

New additions to Morrone's lexicon now include words like croski and mazza, along with some very Toronto-sounding phrases like "You're so cheesy" and "That's Gerber, fam."

However, not everyone was on board with Morrone's newly acquired slang. One X user wrote, "Nobody in the entire history of this city has ever thrown together the sentence 'two twos my word croski.'"

In addition to slang, DiMarco even taught Morrone the proper pronunciation of Toronto, omitting the second T (which, locals know, stands for "tourist"), knowledge she passed on to U.S. late-night TV audiences this week.

"Well, he's from Canada, and he taught me about Toronto slang. But if you're from Toronto, you say 'Toronno,' which I didn't know. Like, if you're from there, you're like, 'Toronno.' I'm probably butchering it, and they're going to, like, kill me. But it's like, 'Toronno,' not 'Toronto.' You don't do both Ts. No way."
