Couple of decades ago I developed a computer system for the Australian Maritime Safety Authority. The Brisbane office used to look after the rostering of pilots on ships. (They did six-week shifts and keeping track of leave entitlements was a major exercise.)
When I presented the finished product, I jokingly called it BOLLARD – Brisbane Office Leave Log And Roster Designer. They liked it; the name stuck.
A much more discreet use of the word than is made by disreputable people who write limericks :)
