Ramius 

Marko Ramius was the captain of a Soviet submarine in the film "The Hunt for Red October" who planned to defect to the United States. In order to ensure that there would be no going back for himself and his officers, he mailed the Soviet high command a letter explaining his intent the day before his launch. In the context of a relationship, to "Ramius" is to purposefully take an action or say something that makes returning to your previous relationship impossible. The most common instance of this is to leave your old relationship for a new one, publicly making this move known to your now ex-girlfriend.

Guy #1: My ex-girlfriend is still really into me, but we haven't been dating for a few weeks now. I am going on a date with a new girl tomorrow night. I don't know if I should tell my ex, because she might never talk to me again.
Guy #2: You should Ramius and tell your ex-girlfriend about it.
Guy #1: OK, I am going to pull a Ramius and tell my ex-girlfriend that I am going to date other people.

Greeting Radius 

The distance of your radius that you will acknowledge the people you know and greet them. Greeting radii almost always depend on person. Usually, your greeting radius varies based on how much you like the person. Someone you are close friends with, will probably have a greeting radius of over 50ft. For people you don't like, it would probably be something like 10ft if it's crowded where you are.

Steve: Oh dude, I had to say hi to Kent today?
Jon: Aww, you said hi to Kunt? He probably thinks you like him now.
Steve: I know, but I kinda used to know him, plus, he got in my greeting radius
Jon: Shit, sucks for you, haha
Steve: Yeah, GOD today was a bad day

underpants radius 

The distance a man is able to comfortably travel (from his bed) without pants; the average radius being just the distance to the shower.

It is theorized that a man's underpants radius is inversely proportional to his confidence; that is, the farther a man travels from his bed in just his underwear, the less he believes in himself.

At first we thought it was funny; at least Marshall didn't left the house without putting pants on. But his underpants radius just kept getting larger. He started getting the paper in his underwear and even going downstairs for a drink in his underwear...!
