One who fears or hates homosexuals, and usually bisexuals.

It seems that most homophobes are rednecks who are members of the Ku Klux Klan.
Homophobia can be very closely compared with racism.
Person 1: "Gay people are fucking stupid"
Person 2: "Stop being a homophobe!"
Person 1: "What, are you some sort of rainbow police looking to ram your pistol into my ass?"
Person 2: "What if I am?! I'm gonna go tell my mother on you!"
Person 1: "Okay."
a) Someone who is secretly gay but doesn't want to admit it so instead, makes fun of gay people so no one suspects that they are actually gay.
