A TV host was interviewing an author, and commenting on the author’s successful book (on the NY Times bestseller list). This seems to be a mashup of “run away with” (win handily) and “off the charts” (spectacular). Both phrases refer to something or someone having success, hence the mixup in context. A big thanks to Verbatim for hearing this one and sending it in.
Speaking of books running away from the charts, check out my malaphor book, “He Smokes Like a Fish and other Malaphors”, available on Amazon. They’re selling like butter! https://www.amazon.com/dp/0692652205
