accident prone

"And then, quite suddenly, Druff began to feel bored. Physically. Bored Physically. As if boredom were a symptom like a tickle in your throat, a fever, or a running nose. Perhaps he'd been exposed to too much MacGuffin. Maybe it was in his bloodstream by now. Gunking up the works. Causing rashes, eruptions, potholing his flesh. Like some disease, say, serious enough in childhood but devastating if you came down with it as an adult".

(Stanley Elkin, The MacGuffin)
