A horny potato
A fat guy who can’t take it anymore and needs to jerk off before he explodes. He’s like a balloon that’s about to pop.
My uncle is a Horny Potato and he’s been trying to jerk off for two hours.
That guy at the gym is a Horny Potato and he’s making a mess of the restrooms.
I told my Horny Potato brother to stop eating and just stroke already.
