R.A.T 

A R.A.T, or Radioactive Agenda Terrorist is someone who spreads Agendas expeditiously. They are considered Radioactive because the Agenda is usually spread in a toxic way. Although they may be terrorizing the internet, specifically YouTube and Twitter, real rats are usually having fun and are being playfully toxic. Alternatively, a lesser known meaning for R.A.T can also be "Rampant Agenda Tyrant", because whenever one starts to talk, it can feel like witnessing a king running rampant with the power of Agenda. You can also be a R.A.T simply by being a supporter of Jay D. Legend on YouTube or Twitch. Rats reside in and thrive in the gutters, which usually is confined to the One Piece community, and the overall anime community as a whole, but as the Don, The Godfather, The Saint said himself, "Nobody is born into this world without an Agenda".
