Wow, can't believe that a) I've never seen this thread before; b) how random some of your handles are and c) that I'm about to resurrect this ancient thread.
Still, most people incorrectly guess the origin of mine, so I'm gonna go right ahead and explain. Back when I was in university, there was a long-running ad campaign for the breakfast cereal Shredded Wheat starring the legendary cricketer Ian Botham. The pitch was always the same for the 20-odd years the campaign ran; Shredded Wheat is good for your heart. The logo was in the shape of a heart, so in uni Shredded Wheat became known as Botham's Love, which evolved into The Love of Botham. Cue all sorts of crude innuendo whenever anyone ate it, eg. "I'm gonna get me some of Botham's Love inside me" and so on.
As it's my favourite cereal, I still think of my housemates from those days whenever I eat it, and it has remained my nickname to this very day.
And it is so obscurely random that it's always available as a username, unlike my common-as-he'll real name!
