What is Yinbo?
Any of a type of nerd who is extremely depressed and questioning of his position in life. Anyone who believes that the only goal of life is to leave their name in the history books. They masturbate frequently to henai porn as well as taking naps during the day while staying up all night to finish homework he hasn't begun yet. He who laughs not, laughs never.
Dude, WTF was up with that Yinbo today? Totally fucked up and shit.
