When this deadline is crossed

This is another mashup from the Merry Malaphorer, Kasie Hunt, heard on MSNBC. It is a conflation of “cross the finish line” (complete a task) and “deadline is passed/missed” In doing a little research on this malaphor, I came across an interesting article on the origin of “deadline” and what “crossing a deadline” literally meant a line or ditch drawn or dug within or around a prison that a prisoner passes at the risk of being shot. Andersonville had such a deadline. Here is the link to the article:

A big thanks to Frank King who heard this one and passed it on!
