I know what you mean.
My service didn’t start until the summer of ‘79, but by then, the “baby killer” thing had been so over used, we had an adaptation of “Jesus Loves The Little Children” song titled “Napalm Burns The Little Children” for cadence while marching.
I know of at least one case of “babyburner” sees use as a password.
“song titled Napalm Burns The Little Children for cadence while marching”....Oh, yeah. Marines fo’ sho’.
(Why didn’t I think of that?)
