Jack+Jill 

So, this is a new, really preppy clothes line, that is similar to Burberry + Polo & Lacoste. Rich black kids wear it because the clothes are hot and the models are hotter. and it is soooo amazing.

The Jack and Jill ad with the group surrounding their BMW got my attention, and then I bought the "Our Group, Our Rules","What Chapter" and the "The Right Club" baby tees at www.jack-and-jill.net. I love the Jack+Jill clothes line. Kisses.

Jacknjellify

jacknjellify is a YouTube account owned by Michael and Cary Huang, who host Battle for BFB (BFB). They are known for their marble races and their BFDI series. The account was founded on February 4, 2008, making animations and marble races. The first episode of BFDI was released on January 1, 2010 and their channel has been running for over ten years. jacknjellify also makes other animations, but BFDI is their main project. Many individuals refuse to watch the series properly, they therefore judge it and the fanbase after watching 6 seconds of the oldest episode.

Someone literally getting crushed to death by their giant ego: "Jacknjellify is dumb because it makes Tiktoks, hurr hurr I'm a stupid reddit cuckhead, funny 69 number is funny.".
An intellectual: "No it's not retard, hundreds of youtube channels (especially those that focus on animation as their primary content) make tiktok accounts in order to sustain popularity between upload, you inchoherent bag of total horse shit".
