In PEOPLE's exclusive sneak peek at Monday's episode, Debbie goes on a first date with a handsome man named Russ who she met online.

"Nervous?" Russ asks. Debbie admits she's feeling butterflies, and he laughs, "I am too."

After complimenting on her matching outfit, Russ suggests the couple dive into a game of mini-golf before leading Debbie to a monster-themed course. As the duo survey the venue, Debbie remarks, "Oh my gosh, it looks like monsters!"

After taking in the gargoyle- and alligator-themed decorations, Debbie and Russ stop in front a troll with a spider resting on its tongue, and Debbie quips, "That reminds me, that looks like my ex!"

After the game begins, Debbie misses a shot on the black carpet and exclaims, "Hot damn, oh man!"

"Just off," she laughs as she reminds her date she hasn't been done anything like this in "more" than five years.

To Debbie's surprise, Russ ends up being a natural. She shouts "holy smokes" when he lands a putt, prompting him to admit he visits the course "every Thursday."

Gearing up for the final putt of the course, Russ stands off to the side, saying suggestively, "Don't mind while I watch." The couple giggle and Debbie flirts, "I may not have a butt Russ, but I've got assets!"

Even after finishing the course, Debbie admits she's "still nervous" about their date.

"You seem more self-assured and maybe well-seasoned," she comments. But Russ says he feels just as uneasy and that his apparent confidence is actually "fake and phony."

"It's very uncomfortable to be in the online world and sifting through mud looking for gold," Debbie notes. "I had a feeling you are real sincere person loyal."

Then she drops a bomb: "But I've told a lie."

Russ gets a nervous look on his face before cautiously asking, "OK, what's your lie?"
