Normal

If you use the word "normal" to describe yourself, you may suffer from the "normal" disease, and you probably identify as a straight white male. However, this disease can also have side effects, the most common being "denial" or "homophobia". If the boy in your class suddenly becomes attractive, you don't have to worry, it's something completely natural and it's most likely not a phase.

"Hey Daniel, what's your sexuality?"

"Ew what the heck, i'm normal."
