Welcome to OHS the worst fucking school in Wisconsin? Oh? Not convinced yet? Search for the schools history of black face and racism scandals. Wanna take a shit in the bathroom? Oop- sorry you can’t, because there is a group of freshman girls vaping in the handy cap stall. Oregon is just a clump of white kids who make the entire white race- correction- human race, look like a failed abortion. Don’t go to Oregon High School if you don’t went to get raped in the tech ed bathroom or catch a nicotine addiction from breathing in the bathroom air.
Have a nicotine addiction at the age of 14? It’s okay, you’re not alone at OHS

"oh and" is the new "p.s."

When used properly, "oh" corresponds to "post" and "and" corresponds to "script".

One may add a second "oh and" by simply putting a second "oh" in the beginning of the statement to designate another afterthought. It should read as follows "oh oh and", which would correspond to "post post script".

In context it should read like the following example:
hey man go check out my new epic youtube vid!

oh and dont forget to rate it!

oh oh and make sure you tell your friends!!
