Jackaleptic
Someone who’s so obsessed with their own junk that they can’t focus on anything else, not even their own life.
My brother is a jackaleptic. He forgot about his own birthday because he was too busy jerking off.
My teacher said I was acting like a jackaleptic during the test. I was too busy jerking off to answer the questions.
My dog is a jackaleptic. He jerks off every time he sees a squirrel.
