The act of ignorantly putting on a condom so that it covers both the shaft and the testicles.
Person 1: I'm so big, even Magnum XLs feel tight. They're roomy around the shaft, but they just don't fit around my balls.
Person 2: What the fuck is wrong with you?
Person 1: What?
Person 2: You're giving yourself a fucking condom nut-hug, you jackass.
