Family sayings
We had one particular word in my family which is best described by way of examples. If somebody did something extremely heinous, or ever so slightly naughty, or even just beat his top score on a computer game, my mother or father would declare that she or he was going to "spiflicate" them, with a varying tone of voice and volume according to the severity of the crime.

Please please please tell me this was a Cockbrush familyism and wasn't shamelessly pilfered from 1970s pop culture...

Hmmm
Not the same meaning though - in my family it was used where others might say "I'll kill him!" or "she's going to get what for"...

I'm horribly afraid...
... that it comes from Ken Dodd and the Diddymen (if that counts as 1970s pop culture??).
