Jackal

A homosexual human male. Also used for human males who may technically be heterosexual (maybe) but who demonstrate tendencies or have clothing peccadilloes which are a little too fancy. Like wearing turtlenecks or a popped polo shirt collar. Also, if deemed a jackal by a majority of people in a room (regardless of whether any of the preceding rules apply)

look he's tucked his check shirt into his mauve chinos, what a jackal
