Kakarotto
Kakarotto is Goku’s real name, which Vegeta still uses to insult him. It’s like calling someone ‘Joe’ when they’re famous as ‘Jr.’
"Kakarotto, you’re still the worst fighter."
Tweet: "Kakarotto is the name of the guy who got beat up by a kid."
DM: "Why do you still call him Kakarotto? He’s not even Saiyan anymore."
