Embrace your inner Ope!
Look up “ope” in the Oxford English Dictionary, you’ll find that the entry is quite an old abbreviation of the word “open,” first used in the approximate year 1275.
Head over to the Urban Dictionary: Ope, it says, is an interjection somewhere between “oops” and “uh-oh” used to express surprise or apology.
Maybe the most comprehensive definition can be found at The School of Ope.
But all of these attempts at definition only serve to limit your Midwestern potential. You do YOUR "Ope" YOUR way and don't let anyone tell you different! That is, if that's okay with everybody else... Oh no, your fine... I'm just gonna scooch over here out of the way.
