ONE-ITIS 

ONE-ITIS
Common symptoms of stage 1 ONE-ITIS are the following:

-thinking she's so much different from any other girl you've ever met.
-thinking she is the most beautiful girl in the world.
-thinking she is to at least some degree innocent and moral. (See definition of a slu.)

Common symptoms of stage 2 ONE-ITIS are the following:

-calling her 2-3x a day, just to talk.
-staying on the phone when she calls you.
-analyzing everything she says and does. Example: "I saw Mary-Slu in the hall today, she looked my way, what did she mean by that???"
-completely ignoring every other girl who shows interest in you.
-asking anyone and everyone for advice and to over-analyze her actions.
-thinking your different from the other 100000000 million "good guy friends" she has. Reality check dbag, YOUR NOT.

You love her even though shes hooked up with all your friends? You suffer from ONE-ITIS.

When a guy devolopes infatuation with a girl he is not involved with, or maybe just a friend thinking he is in love with that girl

I love that girl, i think she is the most beutiful girl in the world. She is funny, loving and I just want to be with her for the rest of my life, to bad she doesn't know me...

The coward's word for love.

Dude 1: Man, I have such a bad case of one-itis for her. How do I break it? What should I do? I'm out of my mind for her. Maybe I should propose.
Dude 2: Nah, you've got to stop talking to her. Don't let her know you care. Find someone else. That's the only way to deal with one-itis.

Nat-one-itis 

The ability to have the worst luck for any given situation, or doing something and having the most negative of reactions

You are in the middle of a divorce, your dog needs surgery, and your car just got stolen? You really do have Nat-one-itis!

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.
