Geoff,
I often heard the term used on the streets of Knightsbridge as a young lad. Legend has it the term was created to describe a phenomenon wherein the top of a seat pillar would strike the bottom of a dilapidated leather saddle. Very undesirable if you will.

Geoff:
You have acurately described the Birkenstalks down the street. Do you know them?
