What is Premorse?
1.
The feeling that you're about to regret something just before you do it anyway (against your better judgment), which is immediately followed by the action and the confirmation that it was a bad idea;
Also shows up as that little voice in your head which says, "I've got a bad feeling about this...."
Just as I had a sense of premorse that I should grab a napkin before eating any more blueberry pie, a giant blue glob fell off of my fork onto my white shirt.
Or, for those who work on cars or other mechanical objects, the sense of premorse that you should reposition your hand, just before the wrench slips and you bang up your knuckles on something hard and painful.
