Someone with Ohio plates who drives in the left lane for miles with no regard for the traffic who wishes to pass. Usually Ohisians drive a mini van but sometimes they can be spotted in a 70's Japanese compact that should have been scrapped in the early 80's.
I would have been home much earlier but this damn Ohisian was in the passing lane for ten miles.

Get the Ohisian mug.
A term used to describe anyone who has originated from Ohio. Main characteristics of an Ohisian are dim-wittedness, telling irrelevant and not funny jokes/stories, mumbling speech, excessive use of the phrase "I seen" + a noun, occasional snorting which usually accompanies a Goofy-esque laugh when something is deeming funny or unusual, and a horrific sense of style.
When Roger told us that ridiculously boring story the other night, I thought, "That guy is SO Ohisian".

The Ohisian woman was consistently made fun of due to her Aqua-Net infused hairstyle, horrifically moo-moo-esque teal cotton dress, and the one can of Budweiser that seemed as if it were glued to her hand all night.
