A Juggernut occurs when someone abstains from ejaculating for a long period of time(both sex and masturbation) until they finally relieve themselves in the most unstoppable and largest nut of their life.
"It had been a month since i last nutted, but I fucked that girl trixie last night and gave her the Juggernut... She was covered from head to toe"
