O-H 

O-H means Original Hipster. Like Jack Kerouac or Jim Morrison. People who have a rockstar-attitude, live on the road, seem to be intlectuals and are heavily intoxicated by alcohol or other kinds of drugs.

Babongo: See that guy? He's lit!
Doejoe: I know that rockstar! He's f****** O-H!

o-h-i-o 

A chant that occurs in Columbus, Ohio between 2 individuals or 2 groups of people who are too stupid to get that not everyone they see gives a rat's ass about sports and can't spell the name of the four letter state they live in without help from other idiots. Proof that OSU students don't learn anything but how to get arrested, drink, fight, watch football and date rape each other. Anyone who yells "O-H" at you in Columbus is a complete waste of flesh and deserves to get their ass kicked.

O-h-i-o? It's a sad state of affairs when spelling the word Ohio is a group effort for homophobic jerks (who attend an institute for higher learning) that spend all their free time watching something as homoerotic as football.
