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."
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.

Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.

Man, I just watched the funniest nutshot video ever.
