Senpai

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!"
