1. RJW is an acronym for the term "Roblox Justice Warrior" which is a reference of a "Social Justice Warrior". The term comes from when children run around on roblox harassing other users for "inappropriate behavior" (aka, something that will cause them to be triggered).

2. RJW is also a person who destroys discord communities that troll roblox moderators or entire groups. They like to find out the accounts of the people in that discord, then proceed to mass report all of them to roblox directly via e-mail. Usually this results in the vast majority of the community getting their account terminated, or given an IP ban.
That damn RJW won't leave us alone.

Short for Ray William Johnson, a Youtuber who runs the show "equals 3" (the =3 face)
