Watch 'The Duff' Stars Bella Thorne And Mae Whitman Test Their Slang Knowledge

It's tough to keep up on all the cool new slang these days, as proven by Bella Thorne and Mae Whitman.

The actresses, who both star in "The DUFF," hung out with DirtyandThirty where they were tested on their slang knowledge. Starting off easy with terms like "bae," the words got progressively more difficult -- especially when they were thrown some curveballs like "O.T.P."

Don't worry, guys -- it's tough to "roll the cobb," but you'll get there eventually.
