Irrelevant foursome 

The 4 ex-friends of Jeffree Star that like to call Jeffree out only when he's not supporting them. (Laura Lee, Nikita Dragun, Manny MUA and Gabriel Zamora)

Here we go again- the irrelevant foursome is trying to call Jeffree names and use him for popularity to compensate for their lack of good content.

The Fantastic Foursome 

A word that commonly refers to the group of Youtubers known as KickthePJ, AmazingPhil, crabstickz, and danisnotonfire. They make pretty much the best videos you'll find on YouTube, so you should probably check them out.

Friend: So, want to go watch some of The Fantastic Foursome's videos?

Me: Of course! What else would I be doing with my time?

Conrad foursome 

A Conrad foursome occurs when two couples hook up in the same room. A common misconception is that a Conrad foursome is an orgy, but as long as the two couples remain separated and each hookup is its own separate entity, the integrity of the Conrad foursome perseveres.

"I heard he had a Conrad foursome with his girlfriend and Julie and Bob last night."

Foursome Sleepover 

A monthly sleepover consisting of Charlie, Natalie, Ava, and Sophia.

Foursome sleepovers follow many traditions such as, blasting Pink Guy , watching weird cartoons, family dinners, getting drunk and crying, falling asleep listening to Lets fighting love, and doing satanic rituals.

The best Foursome sleepovers are at Debis house or in a tent.

Oh no, the foursome is having another sleepover.

The neighbors filed a noise complaint during the foursome sleepover when they wouldn’t stop screaming Nickelodeon girls.
