A man who shares many traits with a piece of human fesces, aka shit. For example, a piece of shit is rarely funny and often appalling to look at. A Hoefly often has a girlfriend he believes to be faithful but who is in actuality a giant cum-guzzling slutwhore.

Also, much as human fesces has a foul odor, a Hoefly also has a foul odor. The noises produced by a defecating human are also similar to the noises produced by a Hoefly.
