An old acquaintance towards whom you are either luke warm or simply ambivalent and who you do not usually wish to engage in casual conversation. As a result your only interaction with this person is a brief "hi," "hello," or perhaps a (rhetorical) "what's up?" or "how's it going" when you happen to see them at the mall or encounter them awkwardly at the company watercooler.
Although I was close to Gabriel in high school, he's just a hi-friend to me now.
