Abbreviation for Son of a Bitch (or is it SOB)
From the original SB.txt
I’ve no idea why I’ve used a picture of Stokes Bay here!
Herb Miller lives in Rowlands Castle with his wife and two cats. He's been collecting SBs for nearly half his lifetime. If you ask him why he’ll say Simply Because. His favourites to date are the short but sweet, palindromic sub bus, the sulphurous brewmasters Googlewhack and of course, seriously bonkers, simply brilliant and silly B. He fully expects his short booklet to become a shortlisted bestseller.
