He’s a walking time bomb

Okay, I said this one the other day, discussing The White Lotus character, Armond. It’s a mashup of “ticking time bomb” (a person, place or thing that at any moment could cause havoc and disastrous results) and “walking disaster” (someone who seems to constantly be in or cause great amounts of trouble). Both idioms describe trouble, for sure. I may also have been thinking of the Erie pizza bomber.
