Lucas Yancey won a rose from Rachel Lindsay on Night 1 as well as the first group-date challenge called "Husband Material" on The Bachelorette.

Lucas, a 30-year-old from Santa Monica, CA, was given the job description "whaboom" by ABC in its cast announcement. Once fans were introduced to Lucas on The Bachelorette, it became clear why that's pretty much his identity.

Lucas screams "whaaaaabooooom" enthusiastically whenever possible, shaking his head and body violently in the process. Rachel seemed to find it hilarious at first, but in her latest blog post, she admitted Lucas had run out of good material.

Rachel's suitors have questioned Lucas' intentions for going on the show, especially Blake Elarbee.

Will Rachel decide to keep one or both men, or maybe she'll send them both packing because of their annoying feud?

Below is a list of 6 facts Reality TV World has compiled about Lucas "Whaboom" Yancey.

- He was born on June 4, 1986 and has a twin brother. He also apparently has a real job working in real estate as a private investor and developer.

Lucas said he owns and manages many properties in Los Angeles as well as in the San Francisco Bay Area.

- Lucas is originally from Woodside, CA, and calls himself an actor, writer, producer and stand-up comedian.

He owns a company called YknotWorld Productions.

- The Bachelorette isn't Lucas' first reality TV experience. He appeared on WE tv's Ex Isle in 2016 with his ex-girlfriend, Brittney. And guess who was also on the reality show? Blake Elarbee!

When Lucas and Brittney decided to date other people, Blake was one of the contestants Brittney hit it off with, so the guys already have history dating the same girl!

That's presumably why Blake had such strong feelings about Whaboom's intentions during The Bachelorette premiere.

- Lucas loves dancing, including tango, swing, ballroom, Russian, freestyle, and the "good old bump and grind."

- Lucas is also fluent in Spanish and appeared on a Spanish-language dating show called 12 Corazones Especial de Circo Entretenimiento, which translates to 12 Hearts Special Circus, on the Telemundo TV network several years ago.

"My first appearance on a #Telemundo TV show. The video footage will be out soon! Como estas tu hamburgesa?," he captioned a February 2013 Instagram photo showing himself with longer hair and a moustache.

- Lucas graduated from UC Berkeley and majored in Legal studies with a focus in Business.

While attending Berkeley, he and his team won 4 Rugby National Championships.
