A Japanese honorific used when someone is older than you in age or they have more experience in a field than you. The opposite being Kouhai

It is usually a troup in anime or manga for a Kouhai to desperately seek their Senpai's attention but fails as because their senpai ignores them continuously.
"Kumagi-senpai was really nice to me today. He even offered me to go drinking with him after work!"

Senpai is an honorific used in Japan towards someone of a higher class than you, almost like a role model. The opposite of senpai is kohai, used towards someone that is of a lower class than you. These terms are used in businesses and wherever else there are rankings in class.
example: Itsuki-senpai, would you like me to print those documents for you?

Also, senpai DOES NOT mean your crush, I'm telling this to all of those people that think senpai means crush.
