I heard Dave Chappelle use it once in an outtake (season 2... Samuel Jackson Beer?). I think he really meant to say mothafucka/motherfucker, and it came out as a Freudian slip.

Micro marriging is when your partner manages your personal day-to-day tasks with you much like a Micro Manager at work.

A word me and my cuz made back when we was but little neds..My big cuz was stoned out her face and continually used the word Futhamucka.. since then its had a grip on me and her.. who have spread it through the whole of Scotland and sevral places in England..

I think you'll find that this phrase has been recreated many times by creative young linguists ... My friends and I used it in the 70's and it was spread by myself in Canada amonsts friends over there in the 80's - also Futhamucker
