Macetein
A person who never stops jerking off for 24 hours straight. They’re like a robot with a hard-on and a permanent smile.
My roommate is a macetein. He’s been jerking off since 3 AM and still going.
This guy must be a macetein. He’s been jerking off in the shower for two hours.
My dog’s owner is a macetein. He jerks off while feeding the dog.
