Babysitters Raging Against Twerps or "B.R.A.T." is an organization of teenage babysitters that Vicky is a part of.
B.R.A.T.'s goal is to torment twerps. Receiving help from a twerp makes B.R.A.T. look weak, and any such member will be banished. When Timmy saved Vicky from a steamroller (he actually wanted to see Vicky get crushed but Wanda yelled at him to save her), Vicky was banished from B.R.A.T., her only friends, and as a result she became obsessively friendly toward Timmy. When Timmy messes around with her enough to make Vicky snap, she beats Timmy up so badly that the B.R.A.T.'s accept Vicky back into their ranks, but Vicky continues her angry tirade and makes herself leader. One day, Vicky took things too far and was using her fellow B.R.A.T.S. as pawns which made them come to their heads seeing that they don't want to go to a level where there's nothing to love anymore, especially Alyssa when she overheard Vicky using Harry Amber as a threat. After her confrontation, the former B.R.A.T.S. decided to shut down business and turn over a new and more peaceful leaf for the rest of their lives.
In an alternate universe where Vicky was never born, the organization is still led by Lauren and has the same acronym, but it's called Babysitters Raging Against Troublemakers, and its goal is to babysit misbehaving children.
