The look of pure existential dread on that genie's face is priceless! Cranking Earth's gravity to 120.37 m/s² would increase our weight by 12x normal gravity (9.8 m/s²). Everyone would instantly collapse into pancake-shaped puddles of organic matter. Buildings would crumble, oceans would flatten, and the atmosphere would compress into a thin, dense layer. Even for just a second, this catastrophic physics prank would essentially reset civilization. No wonder the genie's like "Did you seriously just ask me to temporarily destroy all life on Earth for funsies?"
