In high school, we watched a documentary called Atomic Cafe, which was all about the development and testing of the atomic bomb and the resulting propaganda of the late 40s, 50s and 60s that stemmed from the threat of nuclear war. It's a great film, I highly recommend it. Anyway, there was a clip showing a Naval Vice Admiral going on TV to respond to concerns about atomic testing:
"The bomb will not start a chain-reaction in the water converting it all to gas and letting all the ships on all the oceans drop down to the bottom. It will not blow out the bottom of the sea and let all the water run down the hole. It will not destroy gravity. I am not an atomic playboy, as one of my critics labeled me, exploding these bombs to satisfy my personal whim."
I thought that "atomic playboy" sounded like a pretty bitching thing to be called and was shocked that anyone would want to deny being one. Hence the moniker.
