a Pinocchio tie

A quote at the end of an article in the Boston Globe jumped out at me this morning.

...Meanwhile, amid the roiling atmosphere of Trump’s young presidency, no theory is too out there to be disbelieved, not even one that holds Trump’s ties are growing ever longer. "I think there could be a Pinocchio thing going on," said Megan Collins, founder of the high-profile Style Girlfriend blog. "Every time he lies it magically grows by half an inch."

What an interesting term, a Pinocchio tie!
