From my wife's daughter on Twitter, a PhD history student at Sheffield University: "Threat of the day from #OldBailey 1785: "By the Holy Ghost I will score you like pork". Followed by "Bad luck and sudden death attend you"."
Witnessed whilst I was in University in '97: "If you don't f**k off, I'll beat you with your own shoes..." This threat was actually carried out too, in hilarious fashion. This lad quite literally rugby tackled the antagonist, pulled off his shoes and proceeded to beat him with them, to the enjoyment of everyone in the S.U.
When my sister was very young and got angry she'd shout "I'll pull your arm off 'til you're dead". My cousin would just shout "STRAWBERRIES!!" - He's Norwegian and that was apparently the rudest sounding word that he knew.
A personal favourite has always been "I will beat you like a ginger step-child" - very cruel, but gets good laughs.
