That one guy nobody invited

That one unwanted person who ALWAYS finds a way to get into your conversations no matter the topic.

You: “Remember that one time back in high school when you-“
Random kid across the room: “I remember that!”
The friend you were talking to: “Oh my gosh it’s that one guy nobody invited”

When you are in the doggy style position and you put your girl in a half nelson.

I was fucking my girl last night and put her in the one arm Louie.

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!

Fill two needs with one deed

To achieve two simultaneous goals with a single action.

A less violent alternative to the phrase 'to kill two birds with one stone'.

I needed to post a letter and buy some bread, so I though I'd fill two needs with one deed and stop at the mailbox on the way to the store.
