Shivved is the past tense of shiv, meaning to stab someone with a makeshift blade—typically a weapon improvised in prison from available materials like a sharpened toothbrush or piece of metal.
The word carries connotations of desperate, close-quarters violence: He got shivved in the yard over a gambling debt.
