Someone who has fingered a femail recently. Comes from the association of the fishy odour of the vagina and Captain birs eye, a well known brand of fish fingers (an edable breadcrummed fishy snack). Said snack was advertised by a bushy white bearded naval Cpt. Therefore the gentleman who has fingered is said to be white bearded Cpt.
John fingered Abby last night, Hay ho Cpt. Birds eye!
