that annoying person who just hangs around you all the time like a fly hanging around a shit.

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.

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.

Those tiny flys you see in the summer that are normally found around the bog or hovering around fruit bowls.
