"Skull-popping" is, I'm unreliably informed, slang in certain parts of the UK for the practice of trepanning one's beloved and engaging in coitus with the resulting cavity; viz, drilling into someone's skull and f**king the hole.
Somewhere in West Yorkshire, some time in the mid-1990s, I am less reliably informed that a local newspaper was observed to carry the following headline:
MORE SKULL POPPING
I choose to believe this is true.
I've never found anything quite as simultaneously hilarious and disheartening in any of my local newspapers.
Tonight I did see, written on a board outside a local paper shop:
DRUNK'S ALLOTMENT RAMPAGE
which came close to replicating those feelings of equisite joy and misanthropic misery the skull-popping headline evoked.
Anyone care to share some recalled examples from their own 'hoods?
