NMIXX's Haewon brought laughter after playfully teasing Girls' Generation's Hyoyeon for struggling to understand popular Korean slang, even joking that her father, born in 1969, knows the expressions.

On November 4, Hyoyeon's YouTube channel *Hyo's Level Up* released a new episode of *Fake Kim Hyoyeon*, featuring Haewon as a guest.

During the episode, the two idols practiced dubbing an animation as part of a comedy skit. However, Hyoyeon became confused when she encountered several trendy expressions in her script.

When Hyoyeon came across the word "Nallijabeth," she asked, *"Isn't this a typo? Shouldn't it be Elizabeth?"*

Haewon explained, *"Don't you know Nallijabeth? It just means things are going crazy."*

Still confused, Hyoyeon asked why people would use such an unusual expression.

*“Because it's funny. If you don't understand that, you can't call yourself a sixth-generation idol,”* Haewon jokingly replied, referring to Hyoyeon's fictional sixth-generation girl group persona in the skit.

The playful teasing continued when Hyoyeon encountered another slang term, "Bamti."

*“What does Bamti mean?”* Hyoyeon asked.

Haewon explained that the expression is used to describe something unattractive, outdated, or simply not good.

Hyoyeon responded that sixth-generation idols supposedly do not use expressions like that, prompting Haewon to explain that the term originally came from an online user's name rather than being a shortened phrase.

After introducing more slang, including "Yar," Haewon continued testing Hyoyeon's knowledge of trendy expressions.

The funniest moment came when the production team asked Haewon what she thought about Hyoyeon's attempts to learn the slang.

Staying in character, Haewon jokingly suggested that Hyoyeon might be better off using the expressions without knowing their meanings.

*“If she's going to use them like that, I think it would be better for the people around her if she didn't know what they meant. At least it would be cute if she used them without understanding,”* Haewon teased.

She then delivered another playful remark.

*“Even my dad, who was born in 1969, knows Yar and Bamti,”* she said.

Their humorous exchange highlighted Haewon's quick wit and Hyoyeon's willingness to play along with the jokes, turning a simple slang lesson into an entertaining moment between the two idols.
