A term combining "NASA" and "asshole." It is used by some flat-earthers to insult NASA and people who know that the pictures obtained from NASA of space (
particularly, of our round earth) are authentic.
Since these pictures directly
contradict their "theory," flat-earthers outright deny their validity, and go on to claim that NASA is a deceitful, malicious tool of
the Illuminati government to control the sheep masses.
Flat-brainer: "You globers have no evidence that the earth is round."
Intelligent person: "Um, yes we do. Like, fucking PHOTOS taken by
satellites."
Flat-brainer: "Moronic sheep. You'll believe anything those nassholes show you."
Intelligent person: "I'm done with you. Seek help now for your paranoid delusions."
Flat-brainer: "Bye nasshole."
