Get the Santa flaws mug.
An ironic term used when someone who doesn’t believe in something has no explanation for it when in fact their logic for not believing in it is itself flawed.
Person 1 “I don’t believe in star signs bro, the horoscopes are overly flawed”

The Fifty Flaw sais if there is 50% chance of something going bad and 50% chance of something going good the bad thing will always happen to you. "It's almost like there is 100% chance of everything going wrong." The acceptance of this "flaw" as plausible is often based on personal experience. It's a very moderate pessimistic claim nothing extreme.
