It originates from anime and manga. It's someone older than you. Someone you look up to. If they give the slightest attention to you, you sort of explode. They are just really admired by you and if you are a senpai, bask in it!

In Japan, senpai (先輩) is a mentor or senior. "Senpai" is roughly equivalent to the Western concept of a mentor, though it does not imply as strong a relationship as these words mean in the West, and the term is used more widely and with greater "give" then the western equivalent term. More simply, it can be translated as "Senior" or "Elder"
