This descriptive malaphor is a congruent conflation of “blew our minds” and “knocked our socks off” (surprised someone thoroughly). It was uttered by scientists when they saw a picture of Charon, Pluto’s largest moon. In my limited research, I found that this actually might be a legitimate phrase in England. But, since this is a U.S. blog, I am treating it as a malaphor. After all, I am the malaphor king. A big planetary thank you to Mike Kovacs, who has now been elevated (or demoted?) to Malaphor Science Correspondent.
