I'm guessing this is an rarely heard colloquial phrase, but I'm thinking its meaning refers to sh*tty behaviors committed by very disturbed individuals. I nominate this phrase to be added to the vast collection of idiomatic phrases, used world wide, but most likely heard only in America.
Thanks ShyStoneFemme
