Openheimer's

The condition in which you think you forgot, or actually forgot, to close something important - your car, front door, stove, etc.

I can't remember if I locked the car. I must be getting Openheimer's.
Damn, I left the car open again. I've got Openheimer's for sure!

Oppenheim, Ny

A village with a very weird name. Most likely a cult but we’ll never know due to the fact residents there partake in the annual Cousin-Dick Sucking Competition that takes place once a year and Up The Ass Day, where you can stick just about anything up there.

Oppenheim, Ny sounds like a nice place to live!
