Joey Lawrence revealed the origins behind "Whoa!," his popular "Blossom" catchphrase, during a recent appearance on HuffPost Live.

"That word was great," Lawrence said. "It's so weird that word has transcended 20 years." Lawrence said he first uttered "whoa" as a joke. "I can only imagine what that word would have been had social media been what it is today. It took off in the course of one night once it hit the airwaves, but with social media, it probably would have been twice as fast."

According to Lawrence, "whoa" was written in the script like a surfer dude would say it -- think Keanu Reeves -- but it wasn't getting any laughs.

"The executive producer came up to me and said, 'Can you try something else? ... People aren't finding it humorous,'" Lawrence explained. "I don't know where that came from! I just tried it once and did this weird thing and people laughed. They laughed tremendously long. We did a second take and they laughed again."

And the rest is TV history.
