JohnDeLanto means in slang: JohnDeLantos are clever, cunning, and can stab you in your back nearly every week. JohnDeLantos are egotistic maniacs and people who elevate things to a level similar to Hitler and Stalin. They are also sociopathic keyboard warriors. Many people are AntiJohnDeLanto, and even a discordbot was named “AntiJohnDeLanto”. The current AntiJohnDeLanto following is almost the entire RCW. (in Slang Dictionary, added by Keegan Little)
