Is the mode of reproduction of gays and lesbians, i.e. they DO NOT produce offspring yet they multiply at an enormous rate.
Some aberrant varieties may produce siblings but ,by MYSTERY, these siblings do not necessarily follow their parent's sexual orientation.
Some may call it "infectious reproduction", "transgender reproduction", or the less famous "mysterious reproduction (often alt name for virgin conception/birth)".
Dude to a gay: You dont get pregnant, how come your population increases?
Gay to dude: Antisexual reproduction.
Nerd: In a "not so far" future, Gays will overwhelm the guys.
Lesbo: Yeah, we'll pwn you!
Gay: Blame it on highly evolved form of reproduction, Antisexual Reproduction.
