A nick-name given to someone who makes your decisions for you, shows up at your house univited, takes your dvd's without warning or giving them back and will fall in love with multiple girls a week.
Usually the first one to dig into the appetizers and the last to offer his cash when the bill comes.
Rubsi also has no problem diming you out, especially to a girl, but will get extremely emotional if you try the same on him.
Will also be spotted at times with a "showtime"
Rubsi: "what are you up to?"
Person 2: "Sitting at my house doing nothing."
Rubsi: "OK sounds good I am coming over to use your pool and take your Outside Providence dvd. I wprobably wont give it back either."
