one track mind

Having a one track mind refers to the instance that there is currently only one specific thing on your mind (which you may or may not make clear to your environment by returning again and again to said thing in conversations).

one-room schoolhouse 

A one-room schoolhouse is a bathroom in a commercial establishment where the sinks, toilets, and urinals (if applicable) are in the same room, not separated by partitions.
The term comes from schools from the early 20th century which were the same way -- one room was the entire building, all grades of student in together.

A: "Let's go to Hook's restraunt."
B: "No, I hate that place. Whenever I have to go to the bathroom, it's a one-room schoolhouse. Someone will be in there and either he doesn't lock the door and I end up walking in on him and usually see him naked or the person does lock the door and I'm stuck awkwardly waiting in the way of the servers leaving the kitchen in full view of the restraunt."

One Punched 

When you knock someone out with one punch, and one punch only. Usually to the face or neck.

That kid was talkin' so much shit, everyone thought he would kick the other kids' ass. Then he got one punched and was out for 4 hours.

One Post Wonder

The people who register on messages boards, post one time, then disappear, never to be seen again.

The post that they post is usually a nonsensical one that only a select few might understand, but normally leaving much to the imagination.

A One Post Wonder may contain anything from smileys, the word "Hi", to the more common spam.

One Post Wonder: Hi! :D

*Leaves*

Member 1: What was that about?

Member 2: I've got no idea.
