Hiro Syndrome

When a totally awesome male character in a book or show starts acting very asshole-ish because of a girl or woman.

"You're just being a jerk because of that stupid Haruhi."
"What, do I look like I have Hiro Syndrome?"

Hiro Syndrome

When a nearly-flawless male character in any form of media (usually a well-liked character or even the fanbase favorite) has a sudden change in personality as a result of a relationship with a female character. This change in personality is "a turn for the worse," making the character unwelcome in the media, and often unliked by the majority of fans.

"I don't get it! Hiro's acting like such a dick just because of that bitch Ayaka!"
"Oh, it's because of Hiro Syndrome."

Hiro and Ando

1.Two random Japanese guys who always hang out together a lot.
2.Any two random Asian guys hanging out together a lot (for people who lack the skills to distinguish Japanese from other Asians). A very small version of the "Asian mafia" found in many schools.

Hey look, there's Hiro and Ando.

hiro protagonist

A cheap hack that takes clever shit from cool books and claims them as his own.

That hiro protagonist on Urbandictionary.com is a fuckin' chump. I wish he could come up w/ some of his own damn material.
