common as buggery

Common as buggery, something very common. Dates back to the chain-gangs (troupes of convicts -ex-poms- often chained together), building roads and other useful improvements in penal Australia. Being all men, and being chained together, buggery (anal sex) was a common past-time.

You won't have problems finding those nails, they're as common as buggery.
