Noun. Refers to the modern-day Homo Sapiens (i.e., humans) that are further divided into a sub-species due to their unique trait of feeling attraction to members of the same sex (i.e., they are a bunch of faggot queer homo super gay bitchboys); Homo Gaypiens evolved from an earlier species, known as Homo Erections.
"Dude, where's those faggots Quinton and Zach at? I want to beat the shit out of those Homo Gaypiens!"
