Often confused with love, this is the feeling that a particular woman is actually special. This is just an illusion; she is the same as the other three or so billion. "Go fuck ten other women" is the most commonly prescribed treatment for this "disease" (hence the "itis"), as it tends to show quite quickly how very alike people are.

In other words, get over yourself and your obsession with that girl, because it's just an illusion. And when you get rejected, don't be depressed. Because there's really not much to worry about.

Dude, you definitely have oneitis for that girl. You've been talking about her nonstop for the past week. Don't you realize she's nothing special, and that you are just being fooled? Snap out of it so you won't be so depressed when she rejects you!

Mickey Black's definition is fucking retarded.

There is only one simple explanation for the term: An unhealthy romantic obsession or fixation for/on one person. This mental disease will often interfere with your ability to attract said person, due to your clingyness.

I'm suffering from oneitis because I have a massive crush on that one girl who works at that one store.

oneitis

John, snap out of your oneitis man. She's not into you.

Oneties

The name of the decade from 2010 to 2019. We've had the noughties, and after 2020 we will have the twenties, so this has to be the most logical name for the one between.

Man: I've had some fun during the noughties!
Other Man: Yes, just think what fun we could have during the oneties!
