Why has In-N-Out removed No. 67 from its menu? The slang taking over America explained

In-N-Out Burger has removed the number "67" from its ordering system after a viral slang trend caused disturbances. Teens, particularly Gen Alpha, swarmed restaurants when order number "67" was called, reacting to the phrase "six seven" originating from a rap song. The chain also removed "69" due to similar reasons.
