AIBU to think that just what this country needs right now is another unit of measurement.
I've been thinking that,along the same lines as a Country Mile and a Plumber's Hour, we could institute a Phallic Length to establish distances such as:
the distance between my rear bumper and the TwuntBehind's front bumper at 70+ mph on the motorway.
the distance between where men are looking for an invisible item and where it actually farking is.
the distance that I would like DH to be sleeping away from me so I can enjoy my own space. 
Has anyone got any other uses for this essential unit of measurement?
