RBK 

A very violent gang, RBK Real Blood Killers is a gang started in the east and is obviously a blood gang. This gang is extremely dangerous if you see one of the members I advise u walk the other way.

Yo you heard that kid from down the street got arrested for murder, Yea it’s so crazy I heard he was part of RBK I would not want any of my kids near any of them members.

RBF 

RBF=Resting Bitch Face. That means to always look either serious, mean, rude or bored when you’re face is neutral, or resting. But this doesn’t mean that people with RBF’s are actually mean, it’s just how their face was made :-D.

Alexandra always has a RBF on display, causing people to shy away from her.

rblxwelfare 

RBLXwelfare is the same as RBLXware, with the main menu having the Family Guy intro, the shop being American Dad's intro, Arcade being the Lefty taunt, updates is Hotel Mario's intro, there's a Fave taunt, the end screen having a song having these two lines: "you was at the club, bottoms up when i first met you", all of these use Warioware's sounds for the music.

Boy: Hey, wanna play RBLXwelfare?
Girl: It's the same as RBLXware!
