A blast from the mid-2010s past is making its way across social media as part of a new trend pulled from the annals of Comedy Central history.

The trend, which originated on TikTok, uses audio pulled from a 2016 episode of the TV sitcom "Broad City," starring Ilana Glazer and Abbi Jacobson. The audio clip was uploaded to TikTok for use in content creation and has since been featured in over 135,000 videos since early October.

Usually, the trend appears as people lipsyncing over the sound of the humorous roughly 12-second exchange.

The sound bite in question is a conversation between two female voices discussing how to behave in a nightclub. Even without any other context, you can tell that perhaps they may not be the most well-versed in cool club behavior. In it, they say:

“Do you know them?”

“No, but in da clurb, we all fam.”

“What?”

“In da clurb, we all fam.”

“I don’t-”

“In the club, we are all family. Are you racist?”

Some TikToks cut the audio off before the final line, depending on the context, but nearly all of them lean heavily into the goofiness of the original scene from which the sound is pulled.

Wondering where the trend all over your feeds came from? Here's what to know.

'In da clurb, we all fam' trend

It appears the sound first made its way to TikTok when comedian Maggie Winters, who goes by TikTok name @saggiesplinters, uploaded it to use in a video posted Oct. 3. In it, she lip-syncs to the now well-circulated audio along with fellow TikToker Connor Woods, who goes by handle @fibulaa.

The video quickly amassed nearly 12 million views, with comments professing their love for the source material and lamenting about often using the quote but no one recognizing it.

Netizens began using the sound for all kinds of life situations, from describing socializing at church and cheering on sports teams to showing off Halloween costumes and trying to stay hip to relate to the younger generations.

In one highly-viewed take on the trend, a user joked about sitting with strangers at a hibachi dinner. In another, a man with Down syndrome jokes about greeting other people with Down syndrome, even if they're strangers.

Celebs and influencers jumped on the trend as well, like popstar Sabrina Carpenter's now hugely viral video with 14.8 million views showing her lip-syncing to the audio with the caption "My 30 year old fans trying to talk to my 12 year old fans."

Carpenter's use of the audio struck a chord with fans, with one commenting, "Sabrina please. my niece said 'You’re allowed to listen to her?' Like girl are YOU?"

Olympic star and American gymnast Stephen Nedoroscik also used the audio in a clip posted by "Dancing With the Stars" partner Rylee Arnold, garnering 6.1 million views. Fans loved what they called the "sassiest" appearance of Stephen yet, with one comment joking, "Stephen has gotten so much better at lipsyncing, you’re training him so well."

Where did the 'in da clurb' quote come from and what is Broad City?

"Broad City" was a comedy television show written by and starring Ilana Glazer and Abbi Jacobson. Running from 2014 to 2019 on Comedy Central, it began as a web series of the same name, which ran from 2009 to 2011.

Based on Glazer and Jacobson's real lives and friendship, the sitcom followed characters Abbi Abrams and Ilana Wexler as they struggled to make it in New York City. The show received critical acclaim and was nominated for several awards.

The viral clip in question comes from Season 3, Episode 7, titled “B&B-NYC," which originally aired on March 20, 2016. In it, Abbi and Ilana list their apartments on a bed and breakfast app to make some extra money. After getting some guests, the pair plan to sleep on the roof of Ilana's apartment building until they leave. However, when that fails, the pair decide to go out and party all night, at one point sneaking into an upscale nightclub.

As they try to blend in with the crowd, the two see some other club-goers appearing to point at and whisper about them. "I think they know we're crashing," says Abbi, at which point Ilana responds, "Watch this" before waving enthusiastically at the fellow partiers, who greet her back. It is then that Ilana and Abbi have the famous exchange.

Other quotes from "Broad City" have previously shown pop culture staying power in the five years since the show stopped airing, including, "I'm only 27. What am I, a child bride?" and Ilana's iconic overuse of "Yas Queen."
