Feckless - repost

I heard somebody called "feckless" today. What the hell is feck? And should we really be ridiculing those with a feck deficiency? I'm sure there's someone out there who has no responsibility for their personal lack of feck. In fact, maybe we should begin to treat it as a medical condition. We could give them a daily dosage of feck to make up for a deficiency. Like Insulin but more important.
