Bogfly

Male who hangs around female toilets in an attempt to smell vaginal odour or ordure, depending on the kink. On spying a woman leaving a convenience, the Bogfly will walk briskly past her, and inhale deeply any smells she is drawing in her wake.

Have you heard? The Ops room Boss is a Bogfly!
