a motherfucker thats so ignorant and naive that the only explanation is that they have a dick jammed up their anus all the time and thats why they cant function like a normal human.

a person that cannot be told they are wrong even if what they said has no substance to support their statement, so all their friends just agree with them inorder to avoid a ignoranus discussion.

pronounced: Igner-anus
Ignoranus: "you know weed kills people, right?"
normal dude: "mmmmmk"

Ignoranus: "gay marriage kills healthy families"
normal dude: "right, that makes total sense"

Igneoranus: "rape should be legal"
normal dude: "you know now that i think about it ur right....................you fuckin ignoranus"
Ignoranus: "I AM right you just dont have the mental capacity to comprehend my intellect"
normal dude: "clearly"
