Science has confirmed that resting bitch face is real, and that it happens in men as often as women.

Resting bitch face, also known as RBF or bitchy resting face, gained attention in 2013 after a Funny or Die video done in the form of a PSA went viral .

But RBF is more than just an Internet meme. It's a certain look that many people recognize, a look the researchers behind the new study say can "make us second guess our every decision when its pointed in our direction."

Some celebrities have been quite open about their struggles with RBF.

When somebody takes a photo and Im in the background of it, and I look at it I do think, Oh my God whats wrong with me ? actress Anna Kendrick said last year on "The Late Late Show With James Corden ."
